Abstract
A device may determine, based on layer 2 protocol information of incoming traffic, whether to forward the traffic as layer 2 traffic or terminate the traffic as layer 3 traffic. The device may receive the incoming traffic as packets of a virtual local area network (VLAN) and may analyze a protocol type included in layer 2 header information of the packets to classify, based on the protocol type, the packets as layer 2 output traffic or layer 3 output traffic. The device may transmit, as layer 2 traffic of the VLAN, those of the packets that are classified as layer 2 output traffic, and may terminate, to layer 3 traffic, those of the packets that are classified as layer 3 output traffic.
