Forwarding multicast packets over different layer-2 segments

摘要

Embodiments of the disclosure are directed to forwarding multicast packets among disparate Virtual Local Area Networks (VLANs). An embodiment receives a multicast packet matching registration criteria of one or more ports and forwards the multicast packet to the one or more ports, wherein the one or more ports are in a different VLAN than a port from which the multicast packet was received.

1. A method for forwarding multicast packets among disparate Virtual Local Area Networks (VLANs), comprising:
receiving a multicast packet matching registration criteria of one or more ports; and forwarding the multicast packet to the one or more ports at layer-2 instead of at an application layer, wherein the one or more ports are in a different VLAN than a port from which the multicast packet was received, and wherein the forwarding is performed at layer-2 by generating a copy of the multicast packet for each of the one or more ports, and, for each copy of the multicast packet, replacing an identifier of a VLAN from which the multicast packet was received with an identifier of a VLAN corresponding to one of the one or more ports.
