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.
