Abstract
A network device includes a memory and a packet forwarding engine. The memory stores a multicast list table, tag descriptor data and layer 2 (L2) encapsulation data. The packet forwarding engine receives a first pointer to an entry in the multicast list table, the entry including a second pointer to the tag descriptor data. The packet forwarding engine utilizes the second pointer to retrieve the tag descriptor data, the tag descriptor data including a third pointer to the encapsulation data. The packet forwarding engine constructs a packet header utilizing the retrieved encapsulation data and appends the packet header to a packet payload for forwarding out of the packet forwarding engine.
