The interface then becomes the OWNER router of the VRRP group and the interface's physical MAC address is changed to that of the owner VRRP group's MAC address. • If multiple VRRP groups are configured on an interface, only one of the VRRP Groups can contain the interface primary or secondary IP address. Configure a Virtual IP address with these commands in the following sequence in the INTERFACE mode. Step 1 Task Configure a VRRP group. 2 Configure virtual IP addresses for this VRID. Command Syntax vrrp-group vrrp-id VRID Range: 1-255 virtual-address ip-address1 [...ip-address12] Range: up to 12 addresses Command Mode INTERFACE INTERFACE -VRID Figure 45-4. Command Example: virtual-address Force10(conf-if-gi-1/1-vrid-111)#virtual-address 10.10.10.1 Force10(conf-if-gi-1/1-vrid-111)#virtual-address 10.10.10.2 Force10(conf-if-gi-1/1-vrid-111)#virtual-address 10.10.10.3 Force10(conf-if-gi-1/1-vrid-111)# Figure 45-5. Command Example Display: show config for the Interface Force10(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 Force10(conf-if-gi-1/1)# Note that the Primary IP address and the Virtual IP addresses are on the same subnet Figure 45-6 shows the same VRRP group configured on multiple interfaces on different subnets. 776 | Virtual Router Redundancy Protocol (VRRP)
