The Virtual Router probe discovers the virtual routers in an IPv4 physical router or switch that contains virtual routers. The Virtual Router probe discovers the following additional information: the physical card on which the virtual router resides, if such information is available, and the virtual router’s interfaces and their associated physical ports. The Virtual Router probe uses vendor-specific MIB information.

The Virtual Router probe creates a Router object for the physical router and for each virtual router, and creates a Switch object for the physical switch. The probe uses the ComposedOfVRs relationship to associate the virtual-router objects with the physical-router or physical-switch object.
