INTERFACE mode
vrrp-group vrid
The VRID range is from 1 to 255.
NOTE: The interface must already have a primary IP address defined and be enabled, as shown
in the second example.

Assign Virtual IP addresses
Virtual routers contain virtual IP addresses configured for that VRRP group (VRID). A VRRP group does not
transmit VRRP packets until you assign the Virtual IP address to the VRRP group.
For more information, refer to
To activate a VRRP group on an interface (so that VRRP group starts transmitting VRRP packets),
configure at least one virtual IP address in a VRRP group. The virtual IP address is the IP address of the
virtual router and does not require the IP address mask.
You can configure up to 12 virtual IP addresses on a single VRRP group (VRID).
The following 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 Networking recommends configuring virtual
IP addresses belonging to the same IP subnet for any one VRRP group.
– For example, 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 either subnet 50.1.1.0/24 or subnet 60.1.1.0/24, but not from both subnets (though
Dell Networking OS allows the same).
• If the virtual IP address and the interface's primary/secondary IP address are the same, the priority on
that VRRP group MUST be set to 255. 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.
