Once BGP is registered with BFD at the protocol level, you need to enable BFD for particular IPv4 or
IPv6 BGP neighbors using the
-> ip bgp neighbor 135.10.10.2 bfd-state enable
-> ipv6 bgp neighbor fe80::2efa:a2ff:fe13:e402 bfd-state enable
The above commands enable BFD for a neighbor with IPv4 address 135.10.10.2 and a neighbor with IPv6
address fe80::2efa:a2ff:fe13:e402. To enable BFD for all BGP neighbors (IPv4 and IPv6), use the
bfd-state all-neighbors
-> ip bgp bfd-state all-neighbors enable
To disable BFD for all configured BGP neighbors, use the ip bgp bfd-state all-neighbors with the
disable keyword, as shown below:
-> ip bgp bfd-state all-neighbors disable
To display the BFD status of IPv4 BGP neighbors, use the
example:
-> show ip bgp neighbors

To display the BFD status of IPv6 BGP neighbors, use the
