ABSTRACT:
A network device provides services for multiple virtual private networks (VPNs) via one or more virtual hosts. For example, a router receives packets from multiple VPNs, and communicates the packets to a service card via a logical interface in accordance with a forwarding information base. A virtual host within the service card processes the packets and provides a service for the network device from which the packet was sent. The virtual host may, for example, provide print services for network devices within a corresponding VPN. The virtual host acts, in essence, as a print server within the corresponding VPN. In this manner, the router may eliminate the need for the customer associated with the VPN to maintain print servers within remote customer sites.
