<p>The present disclosure describes methods and network devices for forwarding a message in a layer 2 edge network that includes an access server device connected to a sender device and a gateway device. Forwarding information, which includes information of destination IP address, destination media access control (MAC) address, destination virtual local area network identifier VLAN ID and destination device ID, is established. A message is received by the access server device from the sender device. The message includes first destination MAC address, first destination IP address, first destination VLAN ID, and first destination device ID. It is determined whether the first destination MAC address of a received message is a MAC address of the gateway device. If the first destination MAC address is determined not to be the MAC address of the gateway device, the received message is forwarded according to the first destination MAC address, first destination VLAN ID and first destination device ID. Otherwise, if the first destination MAC address is determined to be the MAC address of the gateway device, second destination MAC address, second destination VLAN ID and second destination device ID associated with the first destination IP address are determined. The message is then modified and forwarded according to the second destination MAC address, second destination VLAN ID, and second destination device ID.</p> |
