Managed Switch CLI Manual, Release 8.0 ip vrrp preempt This command sets the preemption mode value for the virtual router configured on a specified interface. The parameter is the virtual router ID, which is an integer from 1 to 255. Default Format Mode enabled ip vrrp preempt Interface Config no ip vrrp preempt This command sets the default preemption mode value for the virtual router configured on a specified interface. Format Mode no ip vrrp preempt Interface Config ip vrrp priority This command sets the priority of a router within a VRRP group. Higher values equal higher priority. The range is from 1 to 254. The parameter is the virtual router ID, whose range is from 1 to 255. The router with the highest priority is elected master. If a router is configured with the address used as the address of the virtual router, the router is called the "address owner." The priority of the address owner is always 255 so that the address owner is always master. If the master has a priority less than 255 (it is not the address owner) and you configure the priority of another router in the group higher than the master's priority, the router will take over as master only if preempt mode is enabled. Default Format Mode 100 unless the router is the address owner, in which case its priority is automatically set to 255. ip vrrp priority Interface Config Routing Commands v1.0, July 2009 4-28
