Deployment Guide

• The neighbor does not inherit the global BFD disable values congured with the bfd all-neighbor
command or congured for the peer group to which the neighbor belongs.
• The neighbor only inherits the global timer values congured with the bfd all-neighbor command:
interval, min_rx, and multiplier.
When you remove the Disabled state of a BFD for a BGP session with a specied 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 congured with the bfd all-neighbor command or congured for the peer
group to which the neighbor belongs.
