Configuring BFD
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 receives forwarding path detection failure messages from BFD.
Note. BFD must be configured and enabled on the participating BGP interfaces. See
Session Parameters" on page 16-11
1
To associate BGP protocol with BFD liveliness detection, register BGP with BFD at the protocol level
using the
ip bgp bfd-state
-> ip bgp bfd-state enable
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:
-> ip bgp bfd-state disable
To verify the BFD status for BGP protocol, you can use the show ip bgp command as shown below:
-> show ip bgp
Admin Status
Operational Status
Autonomous System Number
BGP Router Id
Confederation Identifier
IGP Synchronization Status
Minimum AS Origin Interval (seconds) = 15,
Default Local Preference
Route Reflection
Cluster Id
Missing MED Status
Aspath Comparison
Always Compare MED
Fast External FailOver
Log Neighbor Changes
Multiple Paths
Graceful Restart
Graceful Restart Status
Configured Graceful Restart Interval = 90s,
IPv4 Unicast
IPv6 Unicast

Once BGP is registered with BFD at the protocol level, you need to enable BFD for particular BGP
neighbors using the
ip bgp neighbor bfd-state
-> ip bgp neighbor 135.10.10.2 bfd-state enable
The above command enables BFD for neighbor with IP address
BGP neighbors, use the
-> 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:

command as shown below:
