ABSTRACT:
Provides is a method for processing a multicast packet received in a system for simultaneously providing virtual interface-based layer-2 multicast switching and layer-3 multicast routing. When a destination MAC address of a received Ethernet frame is a multicast MAC address, a VLAN-based layer-2 multicast switching function is performed. When a destination IP address of a received Ethernet frame is a multicast IP address, a virtual interface-based layer-3 multicast routing function is simultaneously performed within the same system.
