Embodiment Construction

[0052] Turning now to the accompanying drawings, refer to figure 1 Looking at the IPv6 routing table entry under the management of RIPng, the IPv6 routing table entry should include the following information: the destination's IPv6 prefix 10, a metric showing the total cost required to send the datagram to the destination 16 , the IPv6 address 24 of the next router on behalf of the next mileage section, the routing change sign 18 for notifying whether the router is changed recently, and the 30-second timer 20 for sending the routing table information to the adjacent routers and twenty two.

[0053] RIPng is a UDP-based protocol, and sends / receives packets at UDP port number 521. A RIPng packet includes three fields, namely a command (request or response) field, a version field, and a routing table entry field.

[0054] Likewise, each routing table entry includes an IPv6 prefix 10, a routing label 12 to separate external routers from internal routers, a prefix length field 1...

Abstract

A routing table management method using interface IDs in IPv6 supporting next-generation routing information protocol to prevent multiple addresses from being specified by managing a routing table using different interface IDs for respective IPv6 router interfaces Congestion caused by routing table management to a single interface. Wherein, the first router assigns a predetermined value to the first field of the routing item, and assigns an interface ID to the second field, thereby generating routing information, and sending the routing information packet containing the routing information to the second router . Then, the second router extracts the first field value of the routing information packet received from the first router, and if the extracted first field value is a predetermined value, extracts the second field value from the received routing information packet. Finally, update the routing information of the routing item with the same interface ID as the extracted second field value to the routing information of the received routing information packet.

Description

[0001] This patent application claims the benefit of Korean Patent Application No. 2002-73232 filed on Nov. 22, 2002, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a routing table management method using interface identifiers (IDs) in Internet Protocol Version 6 (IPv6), and more particularly to a routing table management method used in IPv6 supporting the Next Generation Routing Information Protocol (RIPng) The routing table management method of interface ID prevents congestion in routing table management caused by multi-source addresses by managing a routing table using different interface IDs for each IPv6 router interface. Background technique [0003] The Internet standard protocol, the computer's Transmission Control Protocol / Internet Protocol (TCP / IP), like other network protocols, has a layered structure known as a protocol stack, protocol suite, or simply a protocol structure. ...
