About MPLS discovery

Edit online

Administrators within service providers who offer Multiprotocol Label Switching (MPLS) VPN services can discover MPLS core networks and MPLS VPNs to enable NOCs within the service provider to monitor the health of customer VPNs.

Network Manager supports the discovery of the following VPNs running across MPLS core networks:

  • Layer 3 VPNs
  • Enhanced Layer 2 VPNs

For the enhanced Layer 2 VPNs, Network Manager discovers point-to-point pseudowires linking two provider edge (PE) routers.

The following sections specify the terminology and topology visualization conventions used in Network Manager to refer to MPLS networks.

Note: The graphics shown in this section are conceptual representations of an MPLS network only. You cannot see these conceptual views in the Network Views graphical user interface (GUI).
