Disabling BFD for BGP
You can disable BFD for BGP.
To disable a BFD for BGP session with a specified neighbor, use the first command. To remove the disabled state of a BFD for BGP
session with a specified neighbor, use the second command.
The BGP link with the neighbor returns to normal operation and uses the BFD session parameters globally configured with the bfd all-
neighbors command or configured for the peer group to which the neighbor belongs.
• Disable a BFD for BGP session with a specified neighbor.
ROUTER BGP mode
neighbor {ip-address | peer-group-name} bfd disable
• Remove the disabled state of a BFD for BGP session with a specified neighbor.
ROUTER BGP mode
no neighbor {ip-address | peer-group-name} bfd disable
Displaying BFD for BGP Information
You can display related information for BFD for BGP.
To display information about BFD for BGP sessions on a router, use the following commands and refer to the following examples.
• Verify a BFD for BGP configuration.
EXEC Privilege mode
show running-config bgp
• Verify that a BFD for BGP session has been successfully established with a BGP neighbor. A line-by-line listing of established BFD
adjacencies is displayed.
EXEC Privilege mode
show bfd neighbors [interface] [detail]
• Check to see if BFD is enabled for BGP connections.
EXEC Privilege mode
show ip bgp summary
• Displays routing information exchanged with BGP neighbors, including BFD for BGP sessions.
EXEC Privilege mode
