Usage

Information

When you enable a BFD session with a specified BGP neighbor or peer group using the bfd neighbor

command, the default BFD session parameters are used (interval: 200 milliseconds, min_rx: 200

milliseconds, multiplier: 3 packets, and role: active) if you have not specified parameters with the bfd

neighbor command.

When you explicitly enable a BGP neighbor for a BFD session with the bfd neighbor command:

● The neighbor does not inherit the global BFD enable 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.

Commands

● neighbor bfd disable — disable a BFD session explicitly with a BGP neighbor or a BGP peer group.

neighbor bfd disable

Explicitly disable a BFD session with a BGP neighbor or a BGP peer group.
