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

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