BGP or MPLS VPN sample configurations

This configuration example describes the additional configuration required to create a sham link
between PE 1 and PE 2 in the example shown in
Figure 83 . In this example, the VRF VPN1 is added
to the loopback interface configuration, and a sham link with a cost of 10 is created between the
loopback interfaces on PE 1 and PE 2.
After this configuration is implemented, routes between CE 2 and CE 3 over the service provider
network is preferred to the backdoor link that exists between these CEs.
PE 1 configuration
Brocade(config)# interface loopback 1
