ABSTRACT:
A routing table management method using an interface ID in the IPv6 that supports RIPng (Routing Information Protocol for next generation), prevents congestion in routing table management because multiple addresses are designated to a single interface, through managing a routing table using a different interface ID for each IPv6 router interface. According to the routing table management method, a first router designates a predetermined value to a first field of a route entry, designates an interface ID to a second field, thereby generating routing information, and a routing information packet including the routing information is transmitted to a second router. Then, the second router extracts a first field value of the received routing information packet from the first router and if the extracted field value is a predetermined value, a second field value is extracted therefrom. Lastly, routing information of a route entry having an interface ID identical with the extracted second field value is updated to routing information of the received routing information packet.
