# Configuring Virtual Routers

Multiple distinct virtual routers are supported within a single router, which allows service providers to configure multiple, separate, secure routers within a single chassis. These routers are identified as virtual routers (VRs). Applications for this function include the creation of individual routers dedicated to wholesale customers, corporate virtual private network (VPN) users, or a specific traffic type.

The router implements the virtual routers by maintaining a separate instance of each data structure for each virtual router and allowing each protocol to be enabled on a case-by-case basis. Virtual routers provide full support for all supported routing protocols (unicast, multicast, and MPLS).
