5. Verify the configuration.
After completing previous configurations, execute the display vpls connection command on the PEs. You
will see that a PW connection in up state has been established.
Configuring BFD in an H-VPLS network to detect errors of the
main link
Network requirements
In the H-VPLS network, Switch A is the UPE, Switch B is the main NPE and Switch C is the backup NPE.
Enable MPLS on the interfaces connecting the switches, and enable OSPF on the switches to ensure
reachability at the network layer.
It is required that when the link between Switch A and Switch B is down, the link failure be detected and
informed to the MPLS LDP protocol for fast PW switchover.
