Command Line Reference Guide

Command History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
When you explicitly disable a BGP neighbor for a BFD session with the neighbor bfd
disable command:
• The neighbor does not inherit the global BFD disable values configured with the bfd
all-neighbors command or configured for the peer group to which the neighbor
belongs.
• The neighbor only inherits the global timer values configured with the bfd all-
neighbors
command: interval, min_rx, and multiplier.
When you remove the disabled state of a BFD for BGP session with a specified neighbor by
entering the no neighbor bfd disable command, the BGP link with the neighbor
returns to normal operation and uses the BFD session parameters globally configured with the
bfd all-neighbors command or configured for the peer group to which the neighbor
belongs.
