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