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.
