virtual-address ip-address1 [...ip-address12]
The range is up to 12 addresses.
Example of the virtual-address Command
FTOS(conf-if-gi-1/1-vrid-111)#virtual-address 10.10.10.1
FTOS(conf-if-gi-1/1-vrid-111)#virtual-address 10.10.10.2
FTOS(conf-if-gi-1/1-vrid-111)#virtual-address 10.10.10.3
FTOS(conf-if-gi-1/1-vrid-111)#
Example of Verifying the Virtual IP Address Configuration
NOTE: In the following example, the primary IP address and the virtual IP addresses are on the same subnet.
FTOS(conf-if-gi-1/1)#show conf
!
interface GigabitEthernet 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
FTOS(conf-if-gi-1/1)#
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.
