8.2.5 show bfd neighbors
This command may be used to verify BFD is properly configured and sessions are established as indicated by
Up in the RH (Remote Heard) and State columns on the Nexus spine and Up in the State column on the
Dell EMC leaf.
Note: The output for S4048-Leaf1 shown is for BGP configurations as indicated by a B in the Clients
column. On OSPF configurations, the output is identical except there is an O in the Clients column. Nexus
spine output is the same for either protocol.
