Reference Guide

These rules apply to virtual IP addresses:
● The virtual IP addresses must be in the same subnet as the primary or secondary IP addresses configured on the interface.
Though a single VRRP group can contain virtual IP addresses belonging to multiple IP subnets configured on the interface,
Dell EMC recommends configuring virtual IP addresses belonging to the same IP subnet for any one VRRP group. An
interface on which you enable VRRP contains a primary IP address of 50.1.1.1/24 and a secondary IP address of 60.1.1.1/24.
The VRRP group (VRID 1) must contain virtual addresses belonging to subnet 50.1.1.0/24 or subnet 60.1.1.0/24.
● If the virtual IP address and the interface’s primary/secondary IP address are the same, the priority of the VRRP group is
set to 255 by default. The interface then becomes the owner router of the VRRP group and the interface’s physical MAC
address changes to that of the owner VRRP group’s MAC address.
● If you configure multiple VRRP groups on an interface, only one of the VRRP groups can contain the interface primary or
secondary IP address.
Configure virtual IP address
Configure the virtual IP address — the primary IP address and the virtual IP addresses must be on the same subnet.
1. Configure a VRRP group in INTERFACE mode (1 to 255).
vrrp-group vrrp-id
2. Configure virtual IP addresses for this VRRP ID in INTERFACE-VRRP mode (up to 10 IP addresses).

Configure virtual IP address
OS10(config)# interface ethernet 1/1/1
