CISCO-OTV-MIB: View SNMP OID List / Download MIB

This MIB module is for configuration & statistic query of Overlay Transport Virtualization (OTV) functionality on Cisco routers and switches. Overlay Transport Virtualization is a Cisco's innovative LAN extension technology. It is an IP-based functionality that provides Layer 2 extension capabilities over any transport infrastructure: Layer 2 based, Layer 3 based, IP switched, label switched, and so on. OTV provides an overlay that enables Layer 2 connectivity between separate Layer 2 domains while keeping these domains independent and preserving the fault- isolation, resiliency, and load-balancing benefits of an IP- based interconnection. OTV introduces the concept of MAC routing, which means a control plane protocol is used to exchange MAC reachability information between network devices providing LAN extension functionality. This is a significant shift from Layer 2 switching that traditionally leverages data plane learning, and it is justified by the need to limit flooding of Layer 2 traffic across the transport infrastructure. OTV also introduces the concept of dynamic encapsulation for Layer 2 flows that need to be sent to remote locations. Each Ethernet frame is individually encapsulated into an IP packet and delivered across the transport network. Finally, OTV provides a native built-in multi-homing capability with automatic detection, critical to increasing high availability of the overall solution. Two or more devices can be leveraged in each data center to provide LAN extension functionality without running the risk of creating an end-to-end loop that would jeopardize the overall stability of the design. The followings detail the OTV specific terminology: Edge Device The edge device performs OTV functions: it receives the Layer 2 traffic for all VLANs that need to be extended to remote locations and dynamically encapsulates the Ethernet frames into IP packets that are then sent across the transport infrastructure. Internal Interfaces To perform OTV functionality, the edge device must receive the Layer 2 traffic for all VLANs that need to be extended to remote locations. The Layer 2 interfaces, where the Layer 2 traffic is usually received, are named internal interfaces. Join Interface The Join interface is used to source the OTV encapsulated traffic and send it to the Layer 3 domain of the data center network. Overlay Interface The Overlay interface is a logical multi-access and multicast- capable interface that must be explicitly defined by the user and where the entire OTV configuration is applied. The following terms are used throughout this MIB: AED Authoritative Edge Device ARP Address Resolution Protocol DNS Domain Name System ISIS Intermediate System to Intermediate System Routing Protocol LSPDB Link State PDU Database OTV Overlay Transport Virtualization VLAN Virtual Local Area Network VPN Virtual Private Network
