Release Information

Command introduced in JunosE Release 7.2.0.
ipv6Address variable added in JunosE Release 8.0.0.


Enables BGP to determine quickly whether a BGP neighbor is unreachable by means of a BFD protocol session to the neighbor address or to each member of the specified peer group. The no version disables BFD liveness detection for the neighbor or peer-group members. The default version removes the explicit configuration from the peer or peer group and reestablishes inheritance of the feature configuration.

Note: BFD sessions might not be maintained when the multiplier value is 1 and configured intervals are very short. We recommend that you do not use a multiplier value of 1 with very short intervals.
