For MPLS discovery, the MPLS Topology Server component of MPLS Manager is able to discover and model the following MPLS entities:

  • TE tunnels and TE LSPs

    Discovers traffic-engineered tunnels and associates backup or secondary TE LSPs with primary TE LSPs; applicable to TE tunnels that are built on Cisco or Juniper M/T devices.

  • P2MP LSPs and subLSPs

    Discovers traffic-engineered point-to-multipoint (P2MP) LSPs and their subLSPs; applicable to P2MP LSPs that are built on Juniper M/T devices that are running JUNOS 9.0 or higher.

  • LDP LSPs

    Discovers any combination of TE LSPs and LDP LSPs in the managed network.

  • Inter-AS LSPs

    Discovers multi-stacked-label LDP LSPs that span multiple autonomous systems; applicable to inter-AS LSPs that are built on Juniper M/T devices.

  • Multi-vendor LSPs

    Discovers TE LSPs and LDP LSPs that are built on a mixture of multi-vendor devices.

  • LSP load balancing

    Discovers multi-path load balancing for LDP LSPs on Juniper M/T devices; disabled by default.

  • LDP adjacencies

    Discovers non-targeted LDP adjacencies for Cisco IOS and Juniper devices.

  • RSVP sessions

    Discovers RSVP sessions for Cisco IOS and Juniper M/T devices.

  • PE and P devices

    Discovers PE and P devices that are implemented on any of the PE- or P-capable devices that are supported by MPLS Manager.

  • CE and multi-VRF CE devices

    Discovers traditional CE devices that are implemented on any of the CE-capable devices that are supported by MPLS Manager.

    Discovers multi-VRF CE devices that are implemented on any of the multi-VRF CE capable Cisco devices that are supported by MPLS Manager.

    All discovery features except LSP load balancing are enabled by default. The enabling parameter for LSP load balancing is “EnableLoadBalancingLSP,” which is described in the MPLS Manager Configuration Guide.

    In addition, the MPLS Topology Server supports the following LSP discovery related features:

  • Automated LSP rediscovery

    Detects the reroute of TE LSPs and subsequently rediscovers the TE LSPs, without the need to perform a full discovery; disabled by default.

    The enabling polling group for this feature is “LSP SNMP Setting,” which is described in the MPLS Manager Configuration Guide.

  • Associate LSP to LDP

    Creates LayeredOver relationship between discovered LDP LSPs that are layered over one or more discovered TE LSPs; enabled by default.

    The enabling parameter for this feature is “ASSOCIATE_LSP_TO_LDP,” which is described in the MPLS Manager Configuration Guide.
