Concept Guide

• The neighbor only inherits the global timer values congured with the bfd neighbor command: interval,
min_rx, and multiplier.
Related Commands
neighbor bfd disable — explicitly disables a BFD session with a BGP neighbor or a BGP peer group.
show bfd neighbors — displays the BFD neighbor information on all interfaces or a specied interface.
neighbor bfd disable
Explicitly disable a BFD session with a BGP neighbor or a BGP peer group.
Syntax
neighbor {ip-address | peer-group-name} bfd disable
Parameters
ip-address Enter the IP address of the BGP neighbor that you want to explicitly disable for BFD
sessions in dotted decimal format (A.B.C.D).
peer-group-name Enter the name of the peer group that you want to explicitly disable for BFD sessions.
Defaults none
Command Modes ROUTER BGP

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 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.
