Creating a Virtual Router
To enable VRRP, create a virtual router. In the Dell Networking Operating System, the virtual router identifier (VRID) identifies a
VRRP group.
To enable or delete a virtual router, use the following commands.
● Create a virtual router for that interface with a VRID.
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.
● Delete a VRRP group.
INTERFACE mode
no vrrp-group vrid
