Command Usage
• The interfaces of all routers participating in a virtual router group must be
within the same IP subnet.
• The IP address assigned to the virtual router must already be configured on
the router that will be the Owner. In other words, the IP address specified in
this command must already exist on one, and only one, router in the virtual
router group, and the network mask for the virtual router address is derived
from the Owner. The Owner will also assume the role of the Master virtual
router in the group.
