MPLS Support


MPLS operates at the network level; that is, the managed objects relevant to MPLS involve more than one node. MPLS nodes have a number of managed objects, the status of which can change over time:

  • Interfaces can be up or down.

  • Routing protocols, such as OSPF, IS-IS, and BGP4, can be operational or disabled.

  • Signaling protocols, such as RSVP-TE and LDP, can be operational or disabled.

  • Forwarding table entries can be active or inactive.

  • LSPs can be up or down.

There are other MPLS objects that do not change because they are static in nature:

  • EROs

  • Resource blocks

  • Cross-connects

All of these are highly relevant to managing MPLS; for example, LSPs may span any number of MPLS nodes and can be built using EROs, resource blocks, and cross-connects. Providing MPLS support requires software for managing these and other objects.

NNM MPLS Support

NNM provides no special support for MPLS but can be extended to use the appropriate MIBs.
