Interface view

Default command level

2: System level

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. The priority-reduced argument ranges

from 1 to 255 and defaults to 10.

Usage guidelines

When the uplink interface of a router in a VRRP group fails, the VRRP group usually 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 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.

Before executing the command, create a VRRP group on an interface and configure the virtual IPv6

address of the VRRP group.

If no interface is specified, the undo vrrp ipv6 vrid track interface command removes the association

between the VRRP group and any interface.

If you configure an interface to be tracked on a router that is the IP address owner in a VRRP group, the

configuration does not take effect. If the router is not the IP address owner in the VRRP group later, the

configuration takes effect.

When the status of the tracked interface turns from down or removed to up, the corresponding router

restores its priority automatically.

The interface specified in this command can be a Layer 3 Ethernet interface, a VLAN interface, a Layer

3 aggregate interface, or an MP-group interface

Examples

# On interface GigabitEthernet 0/1, set the interface to be tracked to GigabitEthernet 0/2, making the

priority of VRRP group 1 on interface GigabitEthernet 0/1 decrement by 50 when GigabitEthernet 0/2

is down or removed.
