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.
