Abstract

The present invention provides a method and device for processing routing entries, the method comprising: determining the first part, the second part of the network part of the ipv6 address and the first virtual routing forwarding instance identifier corresponding to the ipv6 address, the first part is The high 32 bits of the network part, and the second part is the low 32 bits of the network part; combining the first part and the first virtual routing forwarding instance identifier to obtain the first combination information, and determining the first prefix index corresponding to the first combination information, Combining the second part with the first prefix index to obtain the second combination information; correspondingly storing the first combination information and the first prefix index in the first routing table to use the first combination information and the first prefix index as the first routing table The routing entry in the second routing table stores the second combination information in the second routing table so that the second combination information is used as a routing entry in the second routing table. The invention solves the problem of waste of storage resources in the storage of ipv6 routes in the related art.

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 ...
