Configuring Bfd For The Main Link In An H-Vpls Network - HP 12500 Series Configuration Manual

After you complete 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 for the main link in an H-VPLS network

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 IP
connectivity.
Configure BFD for the link between Switch A and Switch B, so when the link is down, BFD can detect the
link failure and inform the MPLS LDP protocol for fast PW switchover.
