ADVERTISEMENT INTERVAL

advertisement-interval

Overview Use this command to configure the advertisement interval of the virtual router.
This is the length of time, in seconds, between each advertisement sent from the
master to its backup(s).
IPv6 VRRP advertisements are sent to the multicast address assigned to the VRRP
group (ff02:0:0:0:0) and a backup virtual router has to join all multicast groups
within this range. VRRP advertisements are sent to a multicast address (ff02::12)
every second by default.
Use the no variant of this command to remove an advertisement interval of the
virtual router, which has been set using the advertisement-interval command,
and revert to the default advertisement interval of 1 second.

interval is configured to a longer time than the VCStacking failover time.
If the VRRPv3 advertisement-interval is shorter than the VCStacking failover time, then
a VRRPv3 failover will also occur whenever a VCStacking failover occurs. Use seconds
not centiseconds to ensure interoperability with VRRPv2.
