Reference Guide

Version 8.4.1.3 Introduced on the E-Series ExaScale.
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.
