Abstract
A network device receives an Ethernet frame sent from an originating device toward a destination device, determines whether the frame includes an Internet Protocol version 6 (IPv6) payload, and determines whether the frame is one of an ingress frame or an egress frame for a virtual local area network (VLAN). The network device determines a VLAN tag for the frame when the frame is an ingress frame and inserts the VLAN tag in a portion of a source internet protocol (IP) address field or a destination IP address field of the IPv6 payload, when the frame is an ingress frame. The network device extracts a VLAN tag from a portion of the source IP address field or a destination IP address field of the IPv6 payload, when the frame is an egress frame. The frame is then output to one of the VLAN or the destination device.
