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.

Commands

• neighbor bfd — enable a BFD session explicitly with a BGP neighbor or a BGP

peer group.
