Abstract
A system and method of routing data packets is disclosed. In a particular embodiment, the method includes receiving a first Internet Protocol (IP) data packet at a first access port of an access line card within a data router. The method also includes transmitting the first IP data packet from the first access port to a network line card within the data router, via a first trunk port of the access line card. The first access port is coupled to the first trunk port and not coupled to at least one other access port. The method further includes receiving a second IP data packet at a second trunk port of the access line card from the network line card. In addition, the method includes transmitting the second IP data packet from the second trunk port to a second access port of the access line card.
