2.4.6 Configure Weighting and
Threshold for VRRP Plus
Backup Group
By configuring different weights for difference devices, those with larger
weights will share more traffic and those with smaller weights will share less
traffic, so that the forwarding capacity of difference devices can be fully
utilized. When the weighting value of BVF device in the backup group is below
the lower threshold, it will automatically quit the forwarding role. When the
weighting value recovers and is beyond the upper threshold, it will
automatically resume the forwarding role.
Command Function
DES-7200(config-if)# vrrp group
weighting maximum [ lower lower ]
[ upper upper ]
Configure weighting and upper/lower
threshold for VRRP Plus backup group
DES-7200(config-if)# no vrrp group
weighting
Restore to the default weighting value of
VRRP Plus backup group (you can input
complete commands, but the value will not
be matched).
Maximum: Weighting value; default value is 100, selecting between 1 and
255;
Lower: Lower threshold of weight; default value is 1, selecting between 1
and (maximum - 1);
Upper: Upper threshold of weight; default value is 100, selecting between
lower and maximum.
2.4.7 Configure Forwarder
Preemption for VRRP Plus
Backup Group
VRRP Plus allows the configuration of forwarder preemption for the backup
group. Configure higher weighting value for device with better forwarding
capacity, so that when the device in listening mode has a weighting value
higher than that of the existing forwarder, the listening device can preempt the
role of such forwarder. In this way, device with better forwarding capacity will
be responsible for packet forwarding and device with lower forwarding
capacity will listen to the status of other devices.
Command Function
DES-7200(config-if)# vrrp group
forwarder preempt
Configure forwarder preemption for VRRP
Plus backup group
