This paper presents a new scheme to accommodate DVMRP multicast capable LAN user into ISP based on IGMP. Currently, it is common that a user premises contains a single host or a LAN with a single segment. More advanced user, however, may introduce LAN with more complex topology and with multicast routing protocol running within its LAN. In order to let ISP have a uniform interface to users, we have been proposing an interworking system which allows ISP to accommodate multicast capable LAN using IGMP. In this paper, we describe the design of the interworking system for DVMRP LAN user.
