R0106-HP MSR Router Series High Availability Command Reference(V7)

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.

For more information about configuring track entries, see High Availability Configuration Guide.

Examples

# Associate the VFs of IPv6 VRRP group 1 on GigabitEthernet 2/0/1 with track entry 1 and decrease the

weights of the VFs in the VRRP group by 50 when the state of track entry 1 changes to negative.
