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 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.
