4. Configure the time interval for
the master in the VRRP group
to send VRRP advertisement.
vrrp ipv6 vrid virtual-router-id timer
advertise adver-interval
Optional.
100 centiseconds by default.
NOTE:
• You might configure different authentication modes and authentication keys for the VRRP
g
roups on an
interface. However, the members of the same VRRP
g
roup must use the same authentication mode and
authentication key.
• Excessive traffic might cause a backup to trigger a change of its status because the backup does not
receive any VRRP advertisements for a specified period of time. To solve this problem, prolon

the time
interval to send VRRP advertisements.
