A multiple shared LAN emulation method in an EPON based on a group ID is provided. A group ID (GID) is defined, and rules for processing an Ethernet frame are defined in each OLT and each ONU using a mode value, an LLID value, and a GID value so that a plurality of LANs are established in the EPON. Thus, a plurality of LANs are established in the OLT, and an independent network is provided to each of a plurality of service providers.
