Service Manual

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-neighbor command or configured for the peer
group to which the neighbor belongs.
