4000 Router Series High Availability Command Reference

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 of an

IPv4 VRRP group.

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

Examples

# Associate the VFs of IPv4 VRRP group 1 on Ethernet 1/1 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.

Parameters

interface interface-type interface-number: Specifies an interface by its type and number.

vrid virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.

verbose: Displays detailed IPv6 VRRP group information. If the verbose keyword is not specified, this

command displays brief IPv6 VRRP group information.

Usage guidelines

If no interface or VRRP group is specified, this command displays the states of all IPv6 VRRP groups. If

only an interface is specified, this command displays the states of all IPv6 VRRP groups on the specified

interface. If both an interface and an IPv6 VRRP group are specified, this command displays the states of

the specified IPv6 VRRP group on the specified interface.
