Example: Configuring VPWS on Local and Remote Routers
The example in this section shows how to configure the VPWS topology illustrated in
Figure 134 on page 659. The example includes procedures for configuring VPWS on both
the local E Series router (PE 1) and the remote E Series router (PE 2).

Topology Overview
The sample topology in Figure 134 on page 659 includes two L2VPNs, L2VPN A and
L2VPN B. L2VPN A connects CE 1, at the edge of Customer A’s Boston site, with CE 3, at
the edge of Customer A’s Chicago site. Similarly, L2VPN B connects CE 2, at the edge
Customer B’s Boston site, with CE 4, at the edge of Customer B’s Chicago site.
The E Series routers in the topology, PE 1 and PE 2, each participate in both L2VPN A and
L2VPN B. The example configures a total of four separate L2VPN instances, one for each
L2VPN on each PE router. The instances for L2VPN A are named l2vpnA, and the instances
for L2VPN B are named l2vpnB.
For each VPWS instance, an Ethernet network interface provides a connection to the
associated CE device.
Each PE router in the sample topology also has an ATM core-facing interface that
connects it to the provider (P) router in the service provider core. You must configure
MPLS LSPs on the core-facing interfaces to connect PE 1 and PE 2 through the P router
across the service provider core. Finally, you must configure BGP on both PE 1 and PE 2
to provide signaling for both L2VPNs.
