The no form of the command reverts to the default value.
Default 1 — Advertisement timer set to 1 second
Parameters seconds — The number of seconds that will transpire before the advertisement timer expires
expressed as a decimal integer.
Values IPv4: 1 — 255
IPv6: 1 — 40
milliseconds milliseconds — Specifies the time interval, in milliseconds, between sending
advertisement messages. This parameter is not supported on the 7750 SR-1 or 7450 ESS-1

Description This command adds a VRRP priority control policy association with the virtual router instance.
To further augment the virtual router instance base priority, VRRP priority control policies can be
used to override or adjust the base priority value depending on events or conditions within the chassis.
The policy can be associated with more than one virtual router instance. The priority events within the
policy either override or diminish the base priority set with the
priority command dynamically
affecting the in-use priority. As priority events clear in the policy, the in-use priority can eventually be
restored to the base
priority value.
The policy command is only available in the non-owner vrrp 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 is used as the in-use priority.
The no form of the command removes existing VRRP priority control policy associations from the
virtual router instance. All associations must be removed prior to deleting the policy from the system.
Default no policy — No VRRP priority control policy is associated with the virtual router instance.
Parameters policy-id — The policy ID of the VRRP priority control expressed as a decimal integer. The vrrp-
policy-id must already exist for the command to function.
Values 1 — 9999
