vrrp ipv6 vrid weight track
Use vrrp ipv6 vrid weight track to configure the VFs in an IPv6 VRRP group to monitor a track entry in
load balancing mode. When the state of the track entry transits to Negative, the weight values of all VFs
in the VRRP group on the router decrease by a specific value.
Use undo vrrp ipv6 vrid weight track to remove the association between the VFs in an IPv6 VRRP group
and a track entry.
Syntax
vrrp ipv6 vrid virtual-router-id weight track track-entry-number [ reduced weight-reduced ]
undo vrrp ipv6 vrid virtual-router-id weight track [ track-entry-number ]
Default
The VFs in an IPv6 VRRP group are not associated with any track entry.

Parameters
virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.
reduced weight-reduced: Reduces the weights of the VFs in the IPv6 VRRP group by a specific value when
the state of the specified track entry changes to negative. The weight-reduced argument is in the range
of 1 to 255.
Usage guidelines
This command is effective only when IPv6 VRRP operates in load balancing mode.
When the state of the track entry transits to Positive or NotReady, the original weight values of the VFs
restore.
By default, the weight of a VF is 255, and its lower limit of failure is 10.
When the weight of a VF owner is higher than or equal to the lower limit of failure, its priority is always
255 and does not change with the weight. To guarantee that an LVF can take over the VF owner as the
AVF when the link of the VF owner fails, the reduced weight for the VF owner must be higher than 245
so the weight of the VF owner can drop below the lower limit of failure.
If the reduced weight-reduced option is not specified, the weights of the VFs in the VRRP group decrease
by 30 when the state of the track entry changes to negative.
You can create a track entry with the track command before or after you associate it with the VFs in an
IPv6 VRRP group.
