Abstract
The present invention relates to a method and an apparatus for performing multicast communication in an ID/locator separation environment. The method includes: receiving a packet; determining whether an entry corresponding to a destination ID included in a packet header of the packet is in a forwarding table; forwarding the packet based on a next hop address included in the entry, if the entry corresponding to the destination ID is present. The entry corresponding to the destination ID can include a plurality of next hop addresses if the destination ID is an ID for a multicast group domain, and the step of forwarding the packet can be carried out by copying the packet by as many as the number of next hop addresses and sending the copied packet to each of the next hop addresses.
