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:
100 milliseconds, min_rx: 100 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.
