Policy-based virtual routing and forwarding (VRF) assignment

摘要

A network switch device includes network interfaces configured to receive and transmit packet based communications within a computer network, a virtual router classification engine, and a packet forwarding engine. The virtual router classification engine is configured to generate a search key for a packet received at a first network interface using header information, and additional information associated with the packet, to select a rule corresponding to the generated search key, and to apply an action associated with the selected rule to the packet. The virtual router classification engine is configured to apply an action associated with the selected rule to the packet at least by assigning a virtual router identifier to the packet. The packet forwarding engine is configured to serve organizations forming the computer network, and segregate packet communications of the first organization from packet communications traffic of other organizations based on the assigned virtual router identifier.
