Verifying the configuration:
# Execute the display vpls connection command on each PE. The output shows that a PW
connection in up state has been established between the PEs.

Configuring BFD for the primary link in an H-VPLS network

Network requirements
In the H-VPLS network, Router A is the UPE, Router B is the primary NPE and Router C is the
backup NPE.
Enable MPLS on the connecting interfaces between the routers, and configure OSPF on the routers
to ensure IP connectivity.
Configure BFD for the link between Router A and Router B and the link between Router A and Router
C so that when either link is down, BFD can detect the link failure and inform the MPLS LDP protocol
for fast PW switchover.
