AlliedWare Plus™ Operating System - Version 5.4.6-1.x
VRRP COMMANDS
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.
Syntax
advertisement-interval [<1-255>|csec <1-4095>]
no advertisement-interval
Default The default advertisement interval is 1 second.
Mode Router Configuration
Usage Note when using VRRP with VCStacking, ensure the VRRP advertisement-interval is
larger than the VCStacking failover time to avoid VCStacking failovers causing
VRRP failovers.
See the VRRP Feature Overview and Configuration Guide for more information
about:
• setting the advertisement-interval when configuring VRRP
• using seconds for VRRPv2 host compatibility whenever you use
transition-mode to upgrade or transition from VRRPv2 to VRRPv3
• VRRPv3 IPv4 configuration details
• VRRPv3 IPv6 configuration details
NOTE: When using VRRPv3 with VCStacking, ensure that the VRRPv3 advertisement-
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.
Parameter Description
<1-255> Specifies the advertisement interval in seconds.
csec Use centiseconds instead of seconds for the advertisement interval.
<1-4095> Specifies the advertisement interval in centiseconds.
