ping-reply configuration.

The ping-reply command is only available in non-owner vrrp virtual-router-id nodal context. If the

ping-reply command is not executed, ICMP echo requests to the virtual router instance IP addresses

will be silently discarded.

The no form of this command restores the default operation of discarding all ICMP echo request

messages destined to the non-owner virtual router instance IP addresses.

policy vrrp-policy-id

config>service>ies>if>ipv6>vrrp

This command creates VRRP control policies. The VRRP policy ID must be created by the policy

command prior to association with the virtual router instance.

The policy command provides the ability to associate a VRRP priority control policy to a virtual

router instance. The policy may be associated with more than one virtual router instance. The priority

events within the policy either override or diminish the base-priority dynamically affecting the in-use

priority. As priority events clear in the policy, the in-use priority may eventually be restored to the

base-priority value.

The policy command is only available in the non-owner vrrp virtual-router-id nodal context. The

priority of owner virtual router instances is permanently set to 255 and cannot be changed by VRRP

priority control policies. For non-owner virtual router instances, if the policy command is not

executed, the base-priority will be used as the in-use priority.

The no form of this command removes any existing VRRP priority control policy association from

the virtual router instance. All such associations must be removed prior to the policy being deleted

from the system.

[no] preempt

config>service>ies>if>ipv6>vrrp

The preempt command provides the ability of overriding an existing non-owner master to the virtual

router instance. Enabling preempt mode is almost required for proper operation of the base-priority

and vrrp-policy-id definitions on the virtual router instance. If the virtual router cannot preempt an

the policy command to be successful.
