After you complete the previous settings, execute the
display vpls connection
command on the PEs.
The command output shows that a PW connection in up state has been established.
Configuring BFD for the primary link in an H-VPLS network
Network requirements
In the H-VPLS network, Switch A is the UPE, Switch B is the primary NPE and Switch C is the backup NPE.
Enable MPLS on the connecting interfaces of the switches. Enable OSPF on the switches to ensure IP
connectivity.
Configure BFD for the link between Switch A and Switch B and the link between Switch A and Switch C,
so that when either link is down, BFD can detect the link failure and inform the MPLS LDP protocol for fast
PW switchover.
