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
neighbor command or configured for the peer group to which the neighbor belongs.
• The neighbor only inherits the global timer values configured with the bfd
neighbor
command: interval, min_rx, and multiplier.
When you remove the disabled state of a BFD for 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 neighbor command or configured for the peer group to which the neighbor belongs.
