Display BFD Information

You can use show commands to display information about BFD sessions and neighbors.

1. Display global BFD information.
   

   device# show bfd
     BFD State: ENABLED, Version: 1
     Supported Protocols: static-ip, ospf6, bgp, ospf
     All Sessions: Current: 181 (Hardware 1, Software 180) Max Allowed: 1000 Max Exceeded Count: 0
   
     Port Sessions     MinTx       MinRx       Mult Sessions
     ====              =====       =====       ==== ========
     Eth 0/1           300         300         3    181
     

2. Display BFD neighbor information for the default VRF.
