Examples of the Configuring and Verifying a Virtual IP Address
The following example shows how to configure a virtual IP address.
Dell(conf-if-te-1/1/1/1-vrid-111)#virtual-address 10.10.10.1
Dell(conf-if-te-1/1/1/1-vrid-111)#virtual-address 10.10.10.2
Dell(conf-if-te-1/1/1/1-vrid-111)#virtual-address 10.10.10.3
The following example shows how to verify a virtual IP address configuration.
NOTE: In the following example, the primary IP address and the virtual IP addresses are on the same subnet.
Dell(conf-if-te-1/1/1/1)#show conf
!
interface TenGigabitEthernet 1/1/1/1
ip address 10.10.10.1/24
!
vrrp-group 111
priority 255
virtual-address 10.10.10.1
virtual-address 10.10.10.2
virtual-address 10.10.10.3
!
vrrp-group 222
no shutdown
The following example shows the same VRRP group (VRID 111) configured on multiple interfaces on different subnets.

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.
