IMPORTANT:
You must create the VRRP
g
roup and assi
g
n a virtual IP address to it before you can associate it with an
y
track entry.
The vrrp ipv6 vrid track command cannot take effect on an IP address owner. If you have confi
g
ured the
command on an IP address owner, the confi
g
uration takes effect after the router chan
g
es to be a non IP
address owner.
You can create a track entry with the track command before or after you associate it with an IPv6 VRRP
group. For more information about configuring track entries, see
High Availability Configuration Guide
.

Examples
# Associate IPv6 VRRP group 1 on GigabitEthernet 0/1 with track entry 1 and decrease the priority of
the router in the VRRP group by 50 when the state of track entry 1 changes to negative.

Parameters
virtual-router-id: VRRP group number, which ranges from 1 to 255.
interface interface-type interface-number: Specifies an interface by its type and number.
reduced priority-reduced: Value by which the priority decrements. priority-reduced ranges from 1 to 255
and defaults to 10.
Description
Use vrrp ipv6 vrid track interface to configure to track the specified interface.
Use undo vrrp ipv6 vrid track interface to disable tracking the specified interface.
By default, no interface is being tracked.
When the uplink interface of a router in a VRRP group fails, usually the VRRP group cannot be aware of
the uplink interface failure. If the router is the master of the VRRP group, hosts on the LAN are not able
to access external networks because of the uplink failure. This problem can be solved by the tracking a
specified uplink interface. When the uplink interface is down or removed, the priority of the master is
automatically decreased by a specified value, allowing a higher priority router in the VRRP group to
become the master.
