VRRP Configuration Command Reference
414 Router Configuration Guide
Description This commands assigns a bi-directional forwarding detect (BFD) session to a given VRRP/SRRP
instance. This BFD sessions provided a heartbeat mechanism that can be used to speed up the transition
of the standby VRRP router to an active state. If the associated BFD session fails, the VRRP routers
will immediately send a VRRP Advertisement message. In addition, the standby VRRP router(s) will
transition to a Master state to speed convergence. The normal VRRP election process will then take
place based on the Advertisement messages sent by all VRRP routers.
There can be only one BFD session assigned to any given VRRP/SRRP instance, but there can be
multiple SRRP/VRRP sessions using the same BFD session.
The parameters used for the BFD sessions are set by the BFD command under the IP interface.
The no form of this command removes BFD from the configuration.
Default none
Parameters service-id — Specifies the service ID of the interface running BFD.
Values service-id:1 to 2147483647
