Configuring BFD Support for BGP
The steps below show how to configure and verify BFD support for the BGP protocol, so that BGP is a
registered protocol with BFD and will receive forwarding path detection failure messages from BFD.
registered protocol with BFD and will receive forwarding path detection failure messages from BFD.
Note. BFD must be configured and enabled on the participating BGP interfaces. See
for more information.
1 To encapsulate BFD within the BGP protocol, register BGP with BFD at the protocol level using the
command as shown below:
-> ip bgp bfd-std status enable
Note. The BFD status for BGP protocol is disabled by default.
The BFD status for the BGP protocol is now enabled, which means that communication between BGP and
BFD is enabled. To de-register BGP with BFD, enter the following command:
BFD is enabled. To de-register BGP with BFD, enter the following command:
-> ip bgp bfd-std status disable
To verify the BFD status for BGP protocol, you can use the
show ip bgp
command as shown below:
-> show ip bgp
2 Once BGP is registered with BFD at the protocol level, you need to enable BFD for particular BGP
neighbors using the
neighbors using the
command as shown below:
-> ip bgp neighbor neigh1 bfd-std enable
The above command enables BFD for neighbor named neigh1. To enable BFD for all BGP neighbors, use
the
the
command as shown below:
-> ip bgp bfd-std all-neighbors
