The following example shows the same VRRP group (VRID 111) configured on multiple interfaces on different subnets. Dellshow vrrp GigabitEthernet 1/1, VRID: 111, Net: 10.10.10.1 State: Master, Priority: 255, Master: 10.10.10.1 (local) Hold Down: 0 sec, Preempt: TRUE, AdvInt: 1 sec Adv rcvd: 0, Bad pkts rcvd: 0, Adv sent: 1768, Gratuitous ARP sent: 5 Virtual MAC address: 00:00:5e:00:01:6f Virtual IP address: 10.10.10.1 10.10.10.2 10.10.10.3 10.10.10.10 Authentication: (none GigabitEthernet 1/2, VRID: 111, Net: 10.10.2.1 State: Master, Priority: 100, Master: 10.10.2.1 (local) Hold Down: 0 sec, Preempt: TRUE, AdvInt: 1 sec Adv rcvd: 0, Bad pkts rcvd: 0, Adv sent: 27, Gratuitous ARP sent: 2 Virtual MAC address: 00:00:5e:00:01:6f Virtual IP address: 10.10.2.2 10.10.2.3 Authentication: When the VRRP process completes its initialization, the State field contains either Master or Backup. Setting VRRP Group (Virtual Router) Priority Setting a virtual router priority to 255 ensures that router is the "owner" virtual router for the VRRP group. VRRP elects the MASTER router by choosing the router with the highest priority. The default priority for a virtual router is 100. The higher the number, the higher the priority. If the MASTER router fails, VRRP begins the election process to choose a new MASTER router based on the next-highest priority. If two routers in a VRRP group come up at the same time and have the same priority value, the interface's physical IP addresses are used as tie-breakers to decide which is MASTER. The router with the higher IP address becomes MASTER. To configure the VRRP group's priority, use the following command. • Configure the priority for the VRRP group. INTERFACE -VRID mode priority priority The range is from 1 to 255. The default is 100. Examples of the priority Command Dell(conf-if-gi-1/2)#vrrp-group 111 Dell(conf-if-gi-1/2-vrid-111)#priority 125 To verify the VRRP group priority, use the show vrrp command.
