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 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.

When you remove the Disabled state of a BFD for a 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 neighbor command or configured 
for the peer group to which the neighbor belongs.
