Creating a Virtual Router
To enable VRRP, create a virtual router. In Dell, the virtual router identier (VRID) identies 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 dened and be enabled, as shown in the second
example.
• Delete a VRRP group.
INTERFACE mode
no vrrp-group vrid
