Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms, and means for interconnecting forwarding contexts using U-turn ports. A U-turn port typically comprises an egress port and an ingress port such that packets placed in the egress port are automatically forwarded to the ingress port. Other forwarding contexts are able to communicate packets to a next-destination forwarding context by sending these packets to the U-turn port of the next-destination forwarding context.
