MPLS RSVP-TE and BFD Cooperation Configuration Example
Network requirements
z
Switch A and Switch B are connected directly. Enable MPLS RSVP-TE BFD on the VLAN
interfaces connecting the two switches, and run OSPF on the switches to ensure reachability at
the network layer.
z
It is required that if the link between Switch A and Switch B fails, BFD can detect the failure
quickly and inform MPLS RSVP-TE of the failure.
