2: System level
Parameters
virtual-router-id: Specifies a VRRP group number, which ranges from 1 to 255.
track track-entry-number: Specifies a track entry. The track-entry-number argument ranges from 1 to
1024.
forwarder-switchover member-ip ipv6-address: Enables the LVF on the device to take over the role of the
AVF at the specified IPv6 address immediately after the specified track entry changes to the negative
state. You can use the display vrrp verbose command to view the IPv6 addresses of VFs.
reduced priority-reduced: Reduces the priority of the device in the VRRP group by a specific value when
the state of the specified track entry changes to the negative state. The priority-reduced argument ranges
from 1 to 255.
switchover: Enables the device 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 device in the VRRP
group decreases by a specified value, or the device immediately takes over as the master if it is a backup
device, or the LVF on the device immediately takes over the role of the AVF at the specified IPv6 address,
depending on your configuration.
If forwarder-switchover member-ip ipv6-address, reduced priority-reduced, and switchover are not
specified, the priority of the device in the VRRP group decreases by 10 when the track entry changes to
negative.
When the track entry changes from negative to positive or invalid, the device automatically restores its
priority.
You must create the VRRP group and assign a virtual IP address to it before you can associate it with any
track entry.
The vrrp ipv6 vrid track command cannot take effect on an IP address owner. If you have configured the
command on an IP address owner, the configuration takes effect after the device changes 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 device in the VRRP group by 50 when the state of track entry 1 changes to negative.

# Associate VRRP group 1 on GigabitEthernet 0/1 with track entry 2 and enable the LVF on the device
to take over the role of the AVF at the IP address of FE80::10 immediately after the specified track entry
changes to the negative state.
