Claim:
1. A method for dual-homed external access in a virtual edge router, the method comprising: receiving a packet on a local area network (LAN) interface of a local host device in the virtual edge router; searching a routing table to identify a remote outgoing interface associated with a destination address of the packet, wherein the destination address of the packet corresponds to an external destination in a private network, and wherein the remote outgoing interface interconnects the private network to a remote host device of the virtual edge router; determining whether the destination address that is associated with the remote outgoing interface is also associated with a local outgoing interface of the local host device after identifying the remote outgoing interface associated with the destination address; and forwarding the packet over the local outgoing interface of the local host device without forwarding the packet to the remote outgoing interface when the destination address is associated with both the local outgoing interface of the local host device and the remote outgoing interface.
