Abstract
Packets are communicated between forwarding contexts (e.g., virtual routers, logical routers, and/or private networks) using virtual interfaces in communications and computing systems, especially routers, packet switching systems, and other devices. A virtual interface refers to the interface infrastructure (e.g., buffers, memory locations, other data structures), but does not connect to an external cable or other communications mechanism such as is a physical interface. Packets are moved between forwarding contexts by automatically moving a packet placed in a first virtual interface associated with a first forwarding context to a second virtual interface associated with a second forwarding context (assuming the packet is not dropped by a feature applied to the packet at the first virtual interface).
