Verify the configuration
After previous configurations, a tunnel is created between Router A and Router C. Issuing the
following command, you will see that the neighbor’s GR status is Ready.

MPLS RSVP-TE and BFD cooperation configuration example
Network requirements
Router A and Router B are connected directly. Enable MPLS RSVP-TE BFD on the interfaces connecting the
two routers, and run OSPF on the routers to ensure reachability at the network layer.
If the physical link between Router A and Router B fails, BFD can detect the failure quickly and inform
MPLS RSVP-TE of the failure.
