The vRtrIsisTable provides an extension of the isisSysTable in the ISIS-MIB.

Each row entry in the vRtrIsisTable represents additional columns for attributes specific to the Alcatel-Lucent SROS series IS-IS protocol instance on this router.

The vRtrIsisLastEnabledTime variable contains the sysUpTime value when isisSysAdminState was last set to enabled (1) to run the IS-IS protocol in the router.

vRtrIsisAuthKey is the authentication key string used to verify the authenticity of packets sent by neighboring routers on an IS-IS interface. For authentication to succeed both the authentication key and the authentication type defined by the vRtrIsisAuthType variable must match. If vRtrIsisAuthType is set to 'password', vRtrIsisAuthKey can include any ASCII character. Authentication can be configured globally and applied to all ISIS levels or it can be configured on a per level basis. The most specific value is used. When read, vRtrIsisAuthKey always returns an Octet String of length zero.

The value of vRtrIsisAuthType indicates the method of authentication used to verify the authenticity of packets sent by neighboring routers on an IS-IS interface.

The value of vRtrIsisOverloadTimeout is the amount of time, in seconds, the router operates in the overload state before attempting to reestablish normal operations. While in overload state, this IS-IS router will only be used if the destination is only reachable via this router; it is not used for other transit traffic. Operationally placing the router into the overload state is often used as a precursor to shutting down the IS-IS protocol operation. This variable is an extension to the isisSysWaitTime to accept an additional value of 0. This value means the router is in overload infinitely.

vRtrIsisOperState indicates the current operating state of this IS-IS protocol instance on this router.

Reference bandwidth - In order to calculate the lowest cost to reach a given destination each configured level on each interface must have a cost.

If the reference bandwidth is configured as Ten Gig (10,000,000,000) a 100-Mbps interface has a default metric of 100. In order for metrics in excess of 63 to be configured wide metrics must be deployed. A value of '0' means that the reference bandwidth is not defined. The maximum value of 1,000,000,000 Kbps amounts to one Terabit per second.

If vRtrIsisIfLevelHelloAuthType is set to 'password', vRtrIsisIfLevelHelloAuthKey can include any ASCII character. Authentication can be configured globally and applied to all ISIS levels or it can be configured on a per level basis. The most specific value is used. If the value of vRtrIsisIfLevelHelloAuthType is 'useGlobal', then the global values, if any, defined in vRtrIsisIfHelloAuthKey and vRtrIsisIfHelloAuthType are used instead. When read, vRtrIsisIfLevelHelloAuthKey always returns an Octet String of length zero.

If vRtrIsisIfLevelPassive has a value of 'true', this interface address is advertised for this level without running the IS-IS protocol on this interface level. While in passive mode, the interface level ignores ingress IS-IS protocol packets and does not transmit any IS-IS protocol packets. If the value of vRtrIsisIfLevelPassive is 'false', this interface address is advertised at this IS-IS level only if it is configured as with the IS-IS protocol as enabled.

The value of vRtrIsisIfLevelTeMetric specifies the metric that is used exclusively by IS-IS traffic engineered traffic. Normal IS-IS traffic specifies metrics values between 1 and 63.

vRtrIsisIfLevelHelloTimer shadows isisCircLevelHelloTimer to have store the values of hello timer in seconds.

The default metric value of this circuit for this level. A value of 0 means that the metric is not configured. In such a case if the vRtrIsisReferenceBw is configured, the value of the metric should be calculated using the formula : Metric = reference-bandwidth / bandwidth. If the vRtrIsisReferenceBw is configured as Ten Gig (10,000,000,000) a 100-Mbps interface has a default metric of 100. In order for metrics in excess of 63 to be configured wide metrics must be deployed. If the reference bandwidth is not configured then all levels will have a default metric of 10. System and loopback interface levels will always have a metric value of 0. The operational value of the metric is maintained in the object vRtrIsisIfLevelOperMetric.

This notification is edge triggered, and should not be regenerated until an address that was used in the previous computation has been dropped.

This notification is generated when we find that and LSP that was stored in memory has become corrupted. We forward an LSP ID. We may have independent knowledge of the ID, but in some implementations there is a chance that the ID itself will be corrupted.

When the sequence number on an LSP we generate wraps the 32 bit sequence counter, we purge and wait to re-announce this information. This notification describes that event. Since these should not be generated rapidly, we generate an event each time this happens. While the first 6 bytes of the LSPID are ours, the other two contain useful information.

A notification sent when we receive a PDU with a different value of the System ID Length. This notification includes the an index to identify the circuit where we saw the PDU and the header of the PDU which may help a network manager identify the source of the confusion. This should be an edge-triggered notification. We should not send a second notification about PDUs received from what seem to be the same source. This decision is up to the agent to make, and may be based on the circuit or on some MAC level information.

A notification sent when we receive a PDU with a different value of the Maximum Area Addresses. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. This should be an edge-triggered notification.

This decision is up to the agent to make, and may be based on the circuit or on some MAC level information.

A notification sent when we receive a Hello PDU from an IS which does not share any area address. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. This should be an edge-triggered notification.

This decision is up to the agent to make, and may be based on the circuit or on some MAC level information.

A notification sent when we receive a Hello PDU from an IS, but do not establish an adjacency due to a lack of resources. This should be an edge-triggered notification. We should not send a second notification about PDUs received from the same source.

A notification sent when we attempt to propagate an LSP which is larger than the dataLinkBlockSize for a circuit. This should be an edge-triggered notification. We should not send a second notification about PDUs received from the same source.

A notification sent when a Level 1 LSP or Level 2 LSP is received which is larger than the local value for isisSysOrigL1LSPBuffSize or isisSysOrigL2LSPBuffSize respectively, or when a Level 1 LSP or Level2 LSP is received containing the originatingLSPBufferSize option and the value in the PDU option field does not match the local value for isisSysOrigL1LSPBuffSize or isisSysOrigL2LSPBuffSize respectively. We pass up the size from the option field or the size of the LSP that exceeds our configuration. This should be an edge-triggered notification. We should not send a second notification about PDUs received from the same source.

A notification sent when a non-pseudonode segment 0 LSP is received that has no matching protocols supported. This may be because the system does not generate the field, or because there are no common elements. The list of protocols supported should be included in the notification: it may be empty if the TLV is not supported, or if the TLV is empty. This should be an edge-triggered notification. We should not send a second notification about PDUs received from the same source.

A notification sent when an adjacency changes state, entering or leaving state up. The first 6 bytes of the vRtrIsisTrapLSPID are the SystemID of the adjacent IS. The isisISAdjState is the new state of the adjacency.
