The vRtrMplsLspTable has an entry for each Labeled Switch Path (LSP) configured for a virtual router in the system.

Each row entry represents a Labeled Switch Path (LSP) configured for a virtual router in the system. Entries can be created and deleted via SNMP SET operations. Setting RowStatus to 'active' requires vRtrMplsLspName to have been assigned a valid value.

The unique value which identifies this Labeled Switch Path (LSP) for this virtual router in the Alcatel 7x50 SR system. It is a unique value among entries with the same value of vRtrID.

The row status used for creation, deletion, or control of vRtrMplsLspTable entries. Before the row can be placed into the 'active' state vRtrMplsLspName must have been assigned a valid value.

The sysUpTime when this row was last modified.

Administrative name for this Labeled Switch Path. The vRtrMplsLspName must be unique within a virtual router instance.

The desired administrative state for this LSP.

The current operational state of this LSP.

Source IP address of this LSP. If vRtrMplsLspFromAddr has not been explicitly set, the system IP address will be used.

Destination IP address of this LSP. This LSP will not be signaled until vRtrMplsLspToAddr is explicitly set.

The vRtrMplsLspType object is an enumerated value that indicates whether the label value is statically or dynamically assigned or whether the LSP will be used exclusively for bypass protection. Enumeration: 'bypass-only': 4, 'unknown': 1, 'static': 3, 'dynamic': 2.

The vRtrMplsLspOutSegIndx is the index value of the entry in the mplsOutSegmentTable associated with this vRtrMplsLspEntry when vRtrMplsLspType is 'static'. If vRtrMplsLspType is 'dynamic', the value of this object will be zero (0).

The value of vRtrMplsLspRetryTimer specifies the time in seconds the software will wait before attempting the establish the failed LSP.

The value of vRtrMplsLspRetryLimit specifies the number of attempts the software should make to reestablish a failed LSP before the LSP is disabled. A value of 0 indicates that an infinite number of retry attempts should be made.

The value of vRtrMplsLspMetric specifies the metric for this LSP which is used to select an LSP among a set of LSPs which are destined to the same egress 7x50 router. The LSP with the lowest metric will be selected. In LDP-over-RSVP, LDP performs a lookup in the Routing Table Manager (RTM) which provides the next hop to the destination PE and the advertising router (ABR or destination PE itself). If the advertising router matches the targeted LDP peer, LDP then performs a second lookup for the advertising router in the Tunnel Table Manager (TTM). This lookup returns the best RSVP LSP to use to forward packets for an LDP FEC learned through the targeted LDP session. The lookup returns the LSP with the lowest metric. If multiple LSPs have the same metric, then the result of the lookup will be to select the first one available in the TTM.

When the value of vRtrMplsLspDecrementTtl is 'true', the ingress ESR writes the TTL of the IP packet into the label and each transit ESR decrements the TTL in the label. At the egress ESR the TTL value from the label is written into the IP packet. When the value of vRtrMplsLspDecrementTtl is 'false', the ingress ESR ignores the IP packet TTL and writes the value of 255 into the label; and the egress ESR does not write the label's TTL into the IP packet.

When the value of vRtrMplsLspCspf is 'true', CSPF computation for constrained-path LSP is enabled. When the value of vRtrMplsLspCspf is 'false' CSPF computation is disabled.

When the value of vRtrMplsLspFastReroute is 'true', fast reroute is enabled. A pre-computed detour LSP is created from each node in the primary path of this LSP. In case of a failure of a link or LSP between two nodes, traffic is immediately rerouted on the pre-computed detour LSP thus avoiding packet loss. Each node along the primary path of the LSP tries to establish a detour LSP as follows: Each upstream node will setup a detour LSP that avoids only the immediate downstream node and merges back onto the actual path of the LSP as soon as possible. The detour LSP may take one or more hops (upto the value of vRtrMplsLspFRHopLimit) before merging back onto the main LSP path. When the upstream node detects a downstream link or node failure, it immediately send traffic for that LSP on the detour path and at the same time signals back to the ingress ESR about the failure. Fast reroute applies only to the primary path of this LSP. No configuration is required on the transit hops of the LSP. The ingress ESR will signal all intermediate ESRs using RSVP to setup their detours. When the value of vRtrMplsLspFastReroute is 'false', fast rerouting is disabled.

The value of vRtrMplsLspFRHopLimit specifies the total number of hops a detour LSP can take before merging back onto the main LSP path.

The value of vRtrMplsLspFRBandwidth specified the amount of bandwidth in mega-bits per second (Mbps) to be reserved for the detour LSP. A value of zero (0) indicates that no bandwidth is reserved.

The name of the class of service value to be assigned to all packets on the LSP is specified with vRtrMplsLspClassOfService. The EXP bits in the MPLS header are set based on the global mapping table that specified the mapping between the forwarding class and the EXP bits. When class of service is specified, all packets will be marked with the same EXP bits that match the vRtrMplsLspClassOfService name in the mapping table. An empty string, ''H, specifies no class of service. Packets are assigned EXP bits based on the same mapping table, however each packet is marked with EXP bits based on the forwarding class from which it is serviced. When the value of vRtrMplsLspPathCosSource is set to 'inherit', the value of vRtrMplsLspClassOfService is applied to that specific LSP/path.

The value of vRtrMplsLspSetupPriority specifies the setup priority to use when insufficient bandwidth is available to setup a LSP. The setup priority is compared against the hold priority of existing LSPs. If the setup priority is higher than the hold priority of the established LSPs, this LSP may preempt the other LSPs. A value of zero (0) is the highest priority and a value of seven (7) is the lowest priority. When the value of vRtrMplsLspPathSetupPriority is set to '-1', the value of vRtrMplsLspSetupPriority is applied to that specific LSP/path.

The value of vRtrMplsLspHoldPriority specifies the hold priority to use when insufficient bandwidth is available to setup a LSP. The setup priority is compared against the hold priority of existing LSPs. If the setup priority is higher than the hold priority of the established LSPs, this LSP may preempt the other LSPs. A value of zero (0) is the highest priority and a value of seven (7) is the lowest priority. When the value of vRtrMplsLspPathHoldPriority is set to '-1', the value of vRtrMplsLspHoldPriority is applied to that specific LSP/path.

When the value of vRtrMplsLspRecord is 'true', recording of all the hops that a LSP traverses is enabled. When the value of vRtrMplsLspRecord is 'false, recording of all the hops that a LSP traverses is disabled.

The value of vRtrMplsLspPreference specifies the preference for the LSP. This value is used for load balancing between multiple LSPs that exist between the same ingress and egress routers. By default, traffic is load balanced among the LSPs, since all LSPs have the same preference. To prefer one LSP over another, change the preference value for that LSP. The LSP with the lowest preference is used. When the value of vRtrMplsLspPathPreference is set to zero (0), the value of vRtrMplsLspPreference is applied to that specific LSP/path.

The value of vRtrMplsLspBandwidth specifies the amount of bandwidth in mega-bits per second (Mbps) to be reserved for the LSP. A value of zero (0) indicates that no bandwidth is reserved. When vRtrMplsLspPathBandwidth is set to -1, the value of vRtrMplsLspBandwidth is applied to that specific LSP/path.

When vRtrMplsLspBwProtect has a value of 'true', bandwidth protection is enabled on a LSP. LSPs that reserve bandwidth will be used for EF services where customers need guaranteed bandwidth. It is expected that multiple EF services will be assigned to a single LSP. When bandwidth protection is enabled on an LSP, each time this LSP is used for a certain service the bandwidth allocated on that service is deducted from the bandwidth reserved for the LSP. Once the bandwidth is exhausted on the LSP, the ESR will provide feedback to the provider indicating that this LSP has exhausted its resources.

The value of vRtrMplsLspHopLimit specifies the maximum number of hops that a LSP will traverse including the ingress and egress ESRs. A LSP will not be setup if the hop limit is exceeded. When the value of vRtrMplsLspPathHopLimit is set to zero (0), the value of vRtrMplsLspHopLimit is applied to that specific LSP/path.

The value of vRtrMplsLspNegotiatedMTU specifies the size for the Maximum transmission unit (MTU) that is negotiated during LSP establishment.

The value of vRtrMplsLspRsvpResvStyle specifies the reservation style for RSVP. The reservation style can be set to 'Shared- Explicit' (se) or 'Fixed-Filter' (ff). Enumeration: 'ff': 2, 'se': 1.

When the value of vRtrMplsLspRsvpAdspec is 'true', the ADSPEC object will be included in RSVP messages. When the value of vRtrMplsLspRsvpAdspec is 'false', the ADSPEC object will not be included in RSVP messages.

The value of vRtrMplsLspFRMethod specifies the fast reroute method used. In the 'One-to-one Backup' method, a backup LSP is established which will intersect the original LSP somewhere downstream of the point of link or node failure. For each LSP that is backed up, a separate backup LSP is established. In the 'Facility Backup' method, instead of creating a separate LSP for every LSP that is to be backed up, a single LSP is created which serves as a backup for a set of LSPs. Such an LSP tunnel is called a 'bypass tunnel'. Enumeration: 'oneToOneBackup': 1, 'facilityBackup': 2.

Setting the value of vRtrMplsLspFRNodeProtect to 'true' enables node protection i.e. protection against the failure of a node on the LSP. Setting the value to 'false' disables node protection.

The value of vRtrMplsLspAdminGroupInclude is a bit-map that specifies a list of admin groups that should be included when this LSP is setup. If bit 'n' is set, then the admin group with value 'n' is included for this LSP. This implies that each link that this LSP goes through must be associated with at least one of the admin groups in the include list. By default, all admin groups are in the include list.

The value of vRtrMplsLspAdminGroupExclude is a bit-map that specifies a list of admin groups that should be excluded when this LSP is setup. If bit 'n' is set, then the admin group with value 'n' is excluded for this LSP. This implies that each link that this LSP goes through must not be associated with any of the admin groups in the exclude list. By default, no admin groups are in the exclude list.

Setting the value of vRtrMplsLspAdaptive to 'true' enables make-before-break functionality for the LSP. When the attributes of an already established LSP are changed, either through manual configuration or due to a change in network topology, make-before-break functionality ensures that the resources of the existing LSP will not be released until a new path (with the same LSP Id) has been established and traffic flowing over the existing path is seamlessly transferred to the new path. Setting the value to 'false' disables make-before-break functionality.

For each writable object in this row that can be configured to inherit its value from the corresponding object in the vRtrMplsGeneralTable, there is bit within vRtrMplsLspInheritance that controls whether to inherit the operational value of the object or use the administratively set value. This object is a bit-mask, with the following positions: vRtrMplsLspOptimizeTimer 0x1 vRtrMplsLspFRObject 0x2 When the bit for an object is set to one, then the object's administrative and operational value are whatever the DEFVAL or most recently SET value is. When the bit for an object is set to zero, then the object's administrative and operational value are inherited from the corresponding object in vRtrMplsGeneralTable.

The value of vRtrMplsLspOptimizeTimer specifies the time, in seconds, the software will wait before attempting to re-optimize the LSP. When CSPF is enabled, changes in the network topology may cause the existing path of a loose-hop LSP to become sub-optimal. Such LSPs can be re-optimized and re-routed through more optimal paths by recalculating the path for the LSP at periodic intervals. This interval is controlled by the optimize timer. A value of 0 indicates that optimization has been disabled. When the vRtrMplsLspOptimizeTimer bit in vRtrMplsLspInheritance is cleared (0), the value returned in the GET request is inherited from vRtrMplsGeneralOptimizeTimer.

The value of vRtrMplsLspOperFastReroute specifies whether the operational LSP has fast reroute enabled or disabled. When make-before-break functionality for the LSP is enabled and if the fast reroute setting is changed, the resources for the existing LSP will not be released until a new path with the new attribute settings has been established. While a new path is being signaled, the administrative value and the operational values of fast reroute setting for the LSP may differ. The value of vRtrMplsLspFastReroute specifies the setting used for the new LSP path trying to be established whereas the value of vRtrMplsLspOperFastReroute specifies the setting for the existing LSP path.

The value of vRtrMplsLspFRObject specifies whether fast reroute, for LSPs using 'Facility Backup', is signalled with or without the fast reroute object. The value of vRtrMplsLspFRObject is ignored if fast reroute is disabled for the LSP or if the LSP is using 'One-to-one Backup'. When the vRtrMplsLspFRObject bit in vRtrMplsLspInheritance is cleared (0), the value returned in the GET request is inherited from vRtrMplsGeneralFRObject.

The value of vRtrMplsLspHoldTimer specifies the time, in seconds, for which the ingress node holds a bit before programming its data plane and declaring the lsp up to the service module. The value of vRtrMplsLspHoldTimer is inherited from the value of vRtrMplsGeneralHoldTimer.

The value of vRtrMplsLspCspfTeMetricEnabled specifies whether the TE metric would be used for the purpose of the LSP path computation by CSPF. When the value of this object is 'false', the IGP metric is used to compute the path of the LSP by CSPF.

The vRtrMplsLspStatTable has an entry for each Labeled Switch Path (LSP) configured for a virtual router in the system.

Each row entry represents a collection of statistics for a Labeled Switch Path (LSP) configured for a virtual router in the system. Entries cannot be created and deleted via SNMP SET operations.

The number of octets that have been forwarded over current LSP active path. The number reported is not realtime, may be subject to several minutes delay. The delay is controllable by MPLS statistics gathering interval, which by default is once every 5 minutes. If MPLS statistics gathering is not enabled, this number will not increment.

The number of packets that have been forwarded over current LSP active path. The number reported is not realtime, may be subject to several minutes delay. The delay is controllable by MPLS statistics gathering interval, which by default is once every 5 minutes. If MPLS statistics gathering is not enabled, this number will not increment.

The age (i.e., time from creation till now) of this LSP in 10-millisecond periods.

The total time in 10-millisecond units that this LSP has been been operational. For example, the percentage up time can be determined by computing (vRtrMplsLspTimeUp/vRtrMplsLspAge * 100 %).

The total time in 10-millisecond units that this LSP has not been operational.

The total time in 10-millisecond units that this LSP's primary path has been operational. For example, the percentage contribution of the primary path to the operational time is given by (vRtrMplsLspPrimaryTimeUp/vRtrMplsLspTimeUp * 100) %.

The number of state transitions (up -> down and down -> up) this LSP has undergone.

The time in 10-millisecond units since the last transition occurred on this LSP.

The time in 10-millisecond units since the last change occurred on this LSP.

The number of paths configured for this LSP.

The number of standby paths configured for this LSP.

The number of operational paths for this LSP. This includes the path currently active, as well as operational standby paths.

voluntary serialization control for vRtrMplsLspPathTable. Primarily used by SNMP manager to coordinate changes to vRtrMplsLspPathInheritance.

The vRtrMplsLspPathTable provides an association between an LSP and a path. An LSP can have more than one path association, but only one of those paths can be specified as the primary path type. Paths are defined in as Tunnel entries in the mplsTunnelTable in the MPLS-TE-MIB.

Each row entry represents an association between a Labeled Switch Path (LSP) in the vRtrMplsLspTable and a path (or tunnel) entry in the mplsTunnelTable. Entries in this table can be created and deleted via SNMP SET operations. Setting RowStatus to 'active' requires vRtrMplsLspPathType to have been assigned a valid value.

The row status used for creation, deletion, or control of vRtrMplsLspPathTable entries. Before the row can be placed into the 'active' state vRtrMplsLspPathType must have been assigned a valid value.

The sysUpTime when this row was last modified.

This variable is an enum that represents the role this path is taking within this LSP. Enumeration: 'standby': 3, 'other': 1, 'primary': 2, 'secondary': 4.

The configured Class Of Service (COS) for this path. If the value is between 0 and 7 inclusive, this value will be inserted in the 3 bit COS field in the label. If the value is 255, the value in the COS field of the label will depend on other factors.

The set of configured properties for this path expressed as a bit map. For example, if the path is an adaptive path, the bit corresponding to bit value 1 is set. Bits: 'cspf': 2, 'adaptive': 1, 'record-route': 0, 'mergeable': 3, 'fast-reroute': 4.

The value of vRtrMplsLspPathBandwidth specifies the amount of bandwidth in mega-bits per seconds (Mbps) to be reserved for this LSP path. A value of zero (0) indicates that no bandwidth is reserved.

When vRtrMplsLspPathBwProtect has a value of 'true', bandwidth protection is enabled on a LSP. LSPs that reserve bandwidth will be used for EF services where customers need guaranteed bandwidth. It is expected that multiple EF services will be assigned to a single LSP. When bandwidth protection is enabled on an LSP, each time this LSP is used for a certain service the bandwidth allocated on that service is deducted from the bandwidth reserved for the LSP. Once the bandwidth is exhausted on the LSP, the ESR will provide feedback to the provider indicating that this LSP has exhausted its resources.

The current working state of this path within this LSP. Enumeration: 'active': 2, 'unknown': 1, 'inactive': 3.

When there is no path in the LSP with vRtrMplsLspPathType value of 'primary', 'secondary' type paths of this LSP with the same value of vRtrMplsLspPathPreference are used for load sharing. When a 'primary' type path exists in the LSP, vRtrMplsLspPathPreference is used to denote at which priority one 'secondary' path will supercede another when the 'primary' fails. 1 indicates the highest priority value. When the vRtrMplsLspPathPreference bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspPreference.

When vRtrMplsLspPathCosSource is set to 'true', the value of vRtrMplsLspPathClassOfService overrides vRtrMplsLspClassOfService. When 'false', the value of vRtrMplsLspClassOfService is used.

The name of the class of service value to be assigned to all packets on the LSP is specified with vRtrMplsLspPathClassOfService. The EXP bits in the MPLS header are set based on the global mapping table that specified the mapping between the forwarding class and the EXP bits. When class of service is specified, all packets will be marked with the same EXP bits that match the vRtrMplsLspPathClassOfService name in the mapping table. An empty string, ''H, specifies no class of service. Packets are assigned EXP bits based on the same mapping table, however each packet is marked with EXP bits based on the forwarding class from which it is serviced.

The value of vRtrMplsLspPathSetupPriority specifies the setup priority to use when insufficient bandwidth is available to setup a LSP. The setup priority is compared against the hold priority of existing LSPs. If the setup priority is higher than the hold priority of the established LSPs, this LSP may preempt the other LSPs. A value of zero (0) is the highest priority and a value of seven (7) is the lowest priority. When the vRtrMplsLspPathHopLimit bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspHopLimit.

The value of vRtrMplsLspPathHoldPriority specifies the hold priority to use when insufficient bandwidth is available to setup a LSP. The setup priority is compared against the hold priority of existing LSPs. If the setup priority is higher than the hold priority of the established LSPs, this LSP may preempt the other LSPs. A value of zero (0) is the highest priority and a value of seven (7) is the lowest priority. When the vRtrMplsLspPathHopLimit bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspHopLimit.

When the value of vRtrMplsLspPathRecord is 'record', recording of all the hops that a LSP traverses is enabled. When the value of vRtrMplsLspPathRecord is 'noRecord', recording of all the hops that a LSP traverses is disabled. Enumeration: 'record': 1, 'noRecord': 2.

The value of vRtrMplsLspPathHopLimit specifies the maximum number of hops that a LSP will traverse including the ingress and egress ESRs. A LSP will not be setup if the hop limit is exceeded. When the vRtrMplsLspPathHopLimit bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspHopLimit.

When vRtrMplsLspPathSharing has a value of 'true', path-sharing is enabled for the secondary path. Path-sharing is used to control the hops of the secondary path. When vRtrMplsLspPathSharing have a value of 'false', CSPF attempts to find a path for the secondary that does not include any node or link that is common to the active primary path. This variable is valid only if vRtrMplsLspPathType is set to 'secondary'.

The desired administrative state for this LSP path.

The current operational state of this LSP path.

For each writable object in this row that can be configured to inherit its value from its corresponding object in the vRtrMplsLspTable, controls whether to inherit the operational value of that object, or use the administratively set value. This object is a bit-mask, with the following positions: vRtrMplsLspPathBandwidth 0x10 vRtrMplsLspPathPreference 0x80 vRtrMplsLspPathSetupPriority 0x400 vRtrMplsLspPathHoldPriority 0x800 vRtrMplsLspPathHopLimit 0x2000 vRtrMplsLspPathAdminGroupInclude 0x20000 vRtrMplsLspPathAdminGroupExclude 0x40000 vRtrMplsLspPathAdaptive 0x80000 vRtrMplsLspPathOptimizeTimer 0x100000 When the bit for an object is set to one, then the object's administrative and operational value are whatever the DEFVAL or most recently SET value is. When the bit for an object is set to zero, then the object's administrative and operational value are inherited from the corresponding object in vRtrMplsLspTable.

This value identifies the label switched path that is signaled for this entry.

The time in 10-millisecond units to signal this path.

Primary index into the mplsTunnelARHopTable identifying a particular recorded hop list. A value of 0 implies that there is no recored hop list associated with this LSP path.

The value of vRtrMplsLspPathNegotiatedMTU specifies the size for the Maximum transmission unit (MTU) that is negotiated during establishment of this LSP Path.

The value of vRtrMplsLspPathFailCode specifies the reason code for LSP Path failure. A value of 0 indicates that no failure has occurred.

The value of vRtrMplsLspPathFailNodeAddr specifies the IP address of the node in the LSP path at which the LSP path failed. When no failure has occurred, this value is 0.

The value of vRtrMplsLspPathAdminGroupInclude is a bit-map that specifies a list of admin groups that should be included when this LSP path is setup. If bit 'n' is set, then the admin group with value 'n' is included for this LSP path. This implies that each link that this LSP path goes through must be associated with at least one of the admin groups in the include list. When the vRtrMplsLspPathAdminGroupInclude bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspAdminGroupInclude.

The value of vRtrMplsLspPathAdminGroupExclude is a bit-map that specifies a list of admin groups that should be excluded when this LSP path is setup. If bit 'n' is set, then the admin group with value 'n' is excluded for this LSP path. This implies that each link that this LSP path goes through must not be associated with any of the admin groups in the exclude list. When the vRtrMplsLspPathAdminGroupExclude bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspAdminGroupExclude.

Setting the value of vRtrMplsLspPathAdaptive to 'true', enables make-before-break functionality for the LSP path. Setting the value to 'false', disables make-before-break functionality for the path. When the vRtrMplsLspPathAdaptive bit in vRtrMplsLspPathInheritance is cleared (0), the value returned to a GET request is inherited from vRtrMplsLspAdaptive.

The value of vRtrMplsLspPathOptimizeTimer specifies the time, in seconds, the software will wait before attempting to re-optimize the LSP path. When CSPF is enabled, changes in the network topology may cause the existing path of a loose-hop LSP to become sub-optimal. Such LSPs can be re-optimized and re-routed through more optimal paths by recalculating the path for the LSP at periodic intervals. This interval is controlled by the optimize timer. A value of 0 indicates that optimization has been disabled. When the vRtrMplsLspPathOptimizeTimer bit in vRtrMplsLspPathInheritance is cleared (0), the value returned in the GET request is inherited from vRtrMplsLspOptimizeTimer.

The value of vRtrMplsLspPathNextOptimize specifies the current value of the optimize timer. This is the time, in seconds, remaining till the optimize timer will expire and optimization will be started for the LSP path.

The value of vRtrMplsLspPathOperBandwidth specifies the amount of bandwidth in mega-bits per seconds (Mbps) that has been reserved for the operational LSP path. When make-before-break functionality for the LSP is enabled and if the path bandwidth is changed, the resources allocated to the existing LSP paths will not be released until a new path with the new bandwidth settings has been established. While a new path is being signaled, the administrative value and the operational values of the path bandwidth may differ. The value of vRtrMplsLspPathBandwidth specifies the bandwidth requirements for the new LSP path trying to be established whereas the value of vRtrMplsLspPathOperBandwidth specifies the bandwidth reserved for the existing LSP path.

Enumeration: 'fail': 4, 'none': 1, 'inProgress': 3, 'success': 2.

Setting the value of vRtrMplsLspPathResignal to 'doAction' triggers the re-signaling of the LSP path. If the LSP path is operationally down either due to network failure or due to the retry attempts count being exceeded, setting this variable to 'doAction' will initiate the signaling for the path. A make-before-break signaling for the path will be initiated if the LSP is operationally up but the make-before-break retry attempts count was exceeded. Make-before-break signaling will also be initiated for any LSP that is operationally up. This may be used to cause a loose-hop LSP to be optimized. If a re-signal is triggered while a re-signaling is already in progress, the old transient state will be destroyed and a new transaction being triggered. An SNMP GET request on this object should return 'notApplicable'.

The sysUpTime when this row was last modified.

When vRtrMplsGeneralAdminState is set to 'inService', the agent attempts to enable the MPLS protocol instance on this router. When vRtrMplsGeneralAdminState is set to 'outOfService', the agent attempts to disable the MPLS protocol instance on this router.

vRtrMplsGeneralOperState indicates the current operating state of this MPLS protocol instance on this router.

When vRtrMplsGeneralPropagateTtl is set to 'true', for all LSPs, the ingress ESR writes the TTL of the IP packet in the label and each transit ESR decrements the TTL in the label. At the egress ESR the TTL value from the label is written into the IP packet. When vRtrMplsGeneralPropagateTtl is set to 'false', the ingress ESR ignores the IP packet TTl and writes the value of 255 into the label, while the egress ESR does not write the label TTL into the IP packet. This assumes that all ESRs have been configured to have vRtrMplsGeneralPropagateTtl set to 'false', or this may result in unpredictable behavior.

This object is used to assign values to vRtrMplsLspIndex as described in 'Textual Conventions for SNMPv2'. The network manager reads the object, and then writes the value back in the SET request that creates a new instance of vRtrMplsLspEntry. If the SET fails with the code 'inconsistentValue', then the process must be repeated. If the the SET succeeds, then the object is incremented and the new instance is created according to the manager's directions.

The value of vRtrMplsGeneralOptimizeTimer specifies the time, in seconds, the software will wait before attempting to re-optimize the LSPs. When CSPF is enabled, changes in the network topology may cause the existing path of a loose-hop LSP to become sub-optimal. Such LSPs can be re-optimized and re-routed through more optimal paths by recalculating the path for the LSP at periodic intervals. This interval is controlled by the optimize timer. A value of 0 indicates that optimization has been disabled. The value for vRtrMplsGeneralOptimizeTimer is by default inherited by all LSPs and their paths.

The value of vRtrMplsGeneralFRObject specifies whether fast reroute, for LSPs using 'Facility Backup', is signalled with or without the fast reroute object.

The value for vRtrMplsGeneralFRObject is by default inherited by all LSPs.

The value of vRtrMplsGeneralResignalTimer specifies the value for the LSP resignal timer, that is the time, in minutes, the software will wait before attempting to resignal the LSPs. When the resignal timer expires, if the new recorded hop list (RRO) for an LSP has a better metric than the current recorded hop list, an attempt will be made to resignal that LSP using the make-before-break mechanism. If the attempt to resignal an LSP fails, the LSP will continue to use the existing path and a resignal will be attempted the next time the timer expires. A value of 0 for the resignal timer indicates that timer-based LSP resignalling has been disabled.

The value of vRtrMplsGeneralHoldTimer specifies the time, in seconds, for which the ingress node holds a bit before programming its data plane and declaring the lsp up to the service module. A value of 0 indicates that the hold timer has been disabled.

When the value of vRtrMplsGeneralSrlgFrr is 'true' the use of SRLG constraint is enabled. By default, the use of SRLG constraint is disabled.

The value of vRtrMplsGeneralSrlgFrrStrict specifies whether to associate the LSP with a bypass or signal a detour if a bypass or detour satisfies all other constraints except the SRLG constraints. When the value of vRtrMplsGeneralSrlgFrrStrict is 'true' and a path that meets SRLG constraints is not found, the bypass or detour is not setup. If this value is set to 'true' when vRtrMplsGeneralSrlgFrr is set to 'false', vRtrMplsGeneralSrlgFrr is set to 'true' also. By default, the value of vRtrMplsGeneralSrlgFrrStrict is 'false'.
