Abstract
A method of presenting different virtual routers to different end users, classes of service, or packets is provided. An incoming packet is received having a VLAN field and at least one additional field. A key is formed from the VLAN field and at least one other packet field, and mapped into a virtual router identifier (VRID) using an indirection mapping process. The VRID identifies a particular virtual router configuration from a plurality of possible virtual router configurations. A networking device is configured to have the particular virtual router configuration identified by the VRID, and the packet is then forwarded by the configured device.
