• The neighbor inherits only the global timer values that are configured with the bfd all-neighbors
command (interval, min_rx, and multiplier).
If you explicitly enable (or disable) a peer group for BFD that has no BFD parameters configured (e.g.
advertisement interval) using the neighbor peer-group-name bfd command, the peer group inherits any
BFD settings configured with the bfd all-neighbors command.
Displaying BFD for BGP Information
To display information about BFD for BGP sessions on a router, enter one of the following show
