Description

It looks like the VRF addition broke a few of the BFD op-mode commands

Note the %Unknown command lines

[email protected]# show protocols bfd
 peer 10.0.10.12 {
     source {
         address 10.0.10.1
     }
 }
[email protected]# run show protocols bfd peer <TAB>
Possible completions:
  <Enter>       Execute the current command
  10.0.10.12    Show Bidirectional Forwarding Detection (BFD) peer status
  counters      Show Bidirectional Forwarding Detection (BFD) peer counters
