R0106-HP MSR Router Series High Availability Command Reference(V7)

49
Large network traffic might disable a backup from receiving VRRP advertisements from the master within
the specified time and trigger an unexpected master switchover. To solve this problem, you can use this
command to configure a larger interval.
Examples
# Configure the master in IPv6 VRRP group 1 to send VRRP advertisements at an interval of 500
centiseconds.

vrrp ipv6 vrid track
Use vrrp ipv6 vrid track to associate an IPv6 VRRP group with a track entry and control master switchover
in the VRRP group in response to changes (such as uplink state changes) detected by the track entry.
Use undo vrrp ipv6 vrid track to remove the association between an IPv6 VRRP group and a track entry.
If no track entry is specified, the association between the VRRP group and any track entry is removed.
Syntax
vrrp ipv6 vrid virtual-router-id track track-entry-number [ reduced priority-reduced | switchover ]
undo vrrp ipv6 vrid virtual-router-id track [ track-entry-number ]
Default
An IPv6 VRRP group is not associated with any track entry.

Parameters
virtual-router-id: Specifies an IPv6 VRRP group number in the range of 1 to 255.
track-entry-number: Specifies a track entry. The track-entry-number argument is in the range of 1 to 1024.
reduced priority-reduced: Reduces the priority of the router in the VRRP group by a specific value when
the state of the specified track entry changes to negative. The priority-reduced argument is in the range
of 1 to 255.
switchover: Enables the router in backup state to take over as the master immediately after the specified
track entry changes to the negative state.
Usage guidelines
When the associated track entry changes to the negative state, the priority of the router in the VRRP group
decreases by a specified value, or the router immediately takes over as the master if it is a backup,
depending on your configuration.
If neither reduced priority-reduced nor switchover is specified, the priority of the router in the VRRP group
decreases by 10 when the track entry changes to negative.
