For a complete listing of all commands related to VRRP, refer to Dell Networking OS Command Line Reference Guide.
Creating a Virtual Router
To enable VRRP, create a virtual router. In Dell, 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
Example of Configuring VRRP
Dell(conf)#int tengig 1/1
Dell(conf-if-te-1/1)#vrrp-group 111
Dell(conf-if-te-1/1-vrid-111)#
Example of Verifying the VRRP Configuration
Dell(conf-if-te-1/1)#show conf
