52
priority reduced [ priority-reduced ]
: Reduces the priority of the router in the VRRP
group by the specified value when the state of the specified track entry changes to Negative. The
value range for the
priority-reduced
argument is 1 to 255, and the default value is 10.
switchover : Enables the router in backup state to take over as the master immediately after the
specified track entry changes to the Negative state.
weight reduced [ weight-reduced ]
: Reduces the weight of all VFs on the router in the
VRRP group by the specified value when the state of the specified track entry changes to Negative.
The value range for the
weight-reduced
argument is 1 to 255, and the default value is 30.
Usage guidelines
When the associated track entry changes to the Negative state, one of the following events occurs
depending on your configuration:
•
The priority of the router in the VRRP group decreases by a specified value.
•
The weight of VFs decreases by a specified value.
•
The router immediately takes over as the master if it is a backup.
•
The LVF on the router immediately takes over the role of the AVF at the specified IPv6 address.
When the track entry changes from Negative to Positive or NotReady, one of the following events
occurs:
•
The router automatically restores its priority or VF weight.
•
The failed master router becomes the master again.
•
The failed AVF becomes active again.
Before executing this command, create an IPv6 VRRP group on the interface and assign a virtual
IPv6 address to the IPv6 VRRP group.
You can create a track entry by using the
track
command before or after you associate it with an
IPv6 VRRP group or the VFs in an IPv6 VRRP group. For more information about configuring track
entries, see
High Availability Configuration Guide .
If no track entry is specified, the
undo vrrp ipv6 vrid track
command removes all
associations between track entries and the IPv6 VRRP group or VFs in the IPv6 VRRP group.
The
vrrp ipv6 vrid track priority reduced
command and the
vrrp ipv6 vrid track
switchover
command do not take effect on an IP address owner. If you configure the command
on an IP address owner, the configuration takes effect after the router changes to be a non-IP
address owner.
The following parameters take effect only when the IPv6 VRRP group is operating in load balancing
mode:
•
The
forwarder-switchover member-ip ip-address
option.
•
The weight reduced weight-reduced option.
•
The
weight reduced
keyword.
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. The priority does not change with the weight. When the upstream link of the VF owner fails, an
LVF must take over as the AVF. The switchover happens when the weight of the VF owner drops
below the lower limit of failure. This requires that the reduced weight for the VF owner be higher than
245.
Examples
# Associate IPv6 VRRP group 1 on VLAN-interface 2 with track entry 1 and decrease the router
priority by 50 when the state of track entry 1 changes to Negative.
