Syntax vrrp ipv6 vrid virtual-router-id track interface interface-type interface-number [ reduced priority-reduced ]

undo vrrp ipv6 vrid virtual-router-id track [ interface interface-type interface-number ]

View Interface view

Parameter virtual-router-id: VRRP standby group number, in the range 1 to 255.

interface interface-typeinterface-number: Specifies an interface by its type and number.

reduced priority-reduced: Specifies the value by which the priority decrements. priority-reducedranges from 1 to 255 and defaults to 10.

Description Use the vrrp ipv6 vrid track command to configure to track the specified interface.

Use the undo vrrp ipv6 vrid track command to disable tracking the specified interface.

By default, no interface is being tracked.

Note that:

■Before executing the command, create a standby group on an interface and configure the virtual IPv6 address of the standby group.

■When the router is the owner of the IP address, you cannot perform the configuration.

■When the status of the tracked interface turns from down 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, or a synchronous/asynchronous serial interface. At present, the layer 2 protocol used by the tracked synchronous/asynchronous serial interfaces can only be PPP protocol.

Example # On interface Ethernet 1/0, set the interface to be tracked as Serial 2/0, making the priority of standby group 1 on interface Ethernet 1/0 decrement by 50 when Serial 2/0 goes down.
