Reference Guide

● The neighbor does not inherit the global BFD disable values configured with the bfd all-
neighbors command or configured for the peer group to which the neighbor belongs.
● The neighbor only inherits the global timer values configured with the bfd all-neighbors
command: interval, min_rx, and multiplier.
When you remove the Disabled state of a BFD for a BGP session with a specified neighbor by entering the
no neighbor bfd disable 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.
