Usage Information
When you explicitly disable a BGP neighbor for a BFD session with the neighbor bfd disable command:
• The neighbor does not inherit the global BFD disable values congured with the bfd neighbor command or
congured for the peer group to which the neighbor belongs.
• The neighbor only inherits the global timer values congured with the bfd neighbor command: interval,
min_rx, and multiplier.
When you remove the Disabled state of a BFD for a BGP session with a specied 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 congured with the bfd neighbor command or congured for the peer group
to which the neighbor belongs.
