Abstract

The invention provides a routing table entry processing method and device. The method comprises the steps of determining a first part and a second part in a network part of an ipv6 address and a firstvirtual routing forwarding instance identifier corresponding to the ipv6 address, wherein the first part is a high 32-bit of the network part, and the second part is a low 32-bit of the network part;combining the first part with the first virtual routing forwarding instance identifier to obtain first combined information, determining a first prefix index corresponding to the first combined information, and combining the second part with the first prefix index to obtain second combined information; and correspondingly storing the first combined information and the first prefix index in a first routing table so as to take the first combined information and the first prefix index as routing table entries in the first routing table, and storing the second combined information in a second routing table so as to take the second combined information as routing table entries in the second routing table. According to the invention, the problem of storage resource waste of ipv6 routing storagein related technologies is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing routing entries. Background technique [0002] At present, the application of ipv6 technology is more and more extensive. The ipv6 address is 128 bits, how to plan, allocate and use the 128-bit ipv6 address is one of the problems to be solved at present. The address prefix of the ipv6 address assigned by the Internet Assigned Numbers Authority (IANA) in the Asia-Pacific region is between 19 and 23 digits, that is, / 19 to / 23. Domains (also known as autonomous systems, AutonomousSystem, or AS for short) have prefixes between / 20 and / 32. For example, China Telecom’s commercial ipv6 is 240e:: / 20, China Unicom’s is 2408:8000:: / 20, and China Radio and Television’s is 240a:4000:: / 21. According to the ipv6 address allocation rules, the prefix of the ipv6 address to the provincial level is / 32, and the network segment address to the user side area ...
