Enhanced Layer 2 MPLS VPNs

For enhanced Layer 2 VPNs, Network Manager provides only an edge view of your MPLS core network.

Network Manager displays an enhanced Layer 2 VPN as a collection of point-to-point pseudowires. This means that if an enhanced Layer 2 VPN contains more than two provider edge (PE) routers, then Network Manager displays that VPN in multiple views, each view consisting of a single PE to PE point-to-point connection.

Table 1 shows examples of enhanced Layer 2 VPNs with two and more than two PEs. The table also provides the number of pseudowires, and hence the number of views that Network Manager displays for each VPN.
