The base priority of an SRRP instance can be managed by VRRP policies. A VRRP policy defines a
set of connectivity or verification tests which, when they fail, may lower an SRRP instances base
priority (creating an in-use priority for the instance). Every time an SRRP instances in-use priority
changes when in master state, it sends an SRRP advertisement message with the new priority. If the
dynamic priority drops to zero or receives an SRRP Advertisement message with a better priority, the
SRRP instance transitions to the becoming backup state.
When the priority command is not specified, or the no priority command is executed, the system uses
a default base priority of 100. The priority command may be executed at anytime.
The no form of the command restores the default base priority to the SRRP instance. If a VRRP
policy is associated with the SRRP instance, it will use the default base priority as the basis for any
modifications to the SRRP instances in-use priority.
Parameters
priority — Specifies a base priority for the SRRP instance to override the default.
