Administrator Guide
• If you configure multiple VRRP groups on an interface, only one of the VRRP Groups can contain the interface primary or secondary IP
address.
Configuring a Virtual IP Address
To configure a virtual IP address, use the following commands.
1. Configure a VRRP group.
INTERFACE mode
vrrp-group vrrp-id
The VRID range is from 1 to 255.
2. Configure virtual IP addresses for this VRID.
INTERFACE -VRID mode
virtual-address ip-address1 [...ip-address12]
The range is up to 12 addresses.
The following example shows how to configure a virtual IP address.
Dell(conf-if-te-1/1/1-vrid-111)#virtual-address 10.10.10.1
Dell(conf-if-te-1/1/1-vrid-111)#virtual-address 10.10.10.2
Dell(conf-if-te-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)#show conf
!
interface TenGigabitEthernet 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.
