Abstract

The invention provides a detection system and method for routing configuration abnormity of an IS-ISv6 network. The system comprises a routing information acquisition device, a message information parsing device, and a routing configuration abnormity detection device. To be specific, the routing information acquisition device adjacent to a layer one-half router of each region of an IS-ISv6 network is used for receiving messages from the neighboring layer one-half routers; the message information parsing device is used for parsing a link state message received by the routing information acquisition device to obtain a TLV field; and the routing configuration abnormity detection device is used for determining whether routing configuration abnormity occurs based on the TLV field obtained based on parsing by the message information parsing device. According to the invention, the routing configuration abnormity of the IS-ISv6 network can be detected; and the real-time performance and reliability of finding of the routing configuration abnormity of the IS-ISv6 network can be guaranteed under the circumstances that no network load is increased.

Description

technical field [0001] The invention relates to the technical field of network measurement, in particular to an IS-ISv6 network routing configuration anomaly detection system and method. Background technique [0002] With the rapid development of the Internet, IPv6 technology has been widely deployed and applied. Currently, the IS-ISv6 dynamic routing protocol (IS-ISv6 protocol for short) is mostly used as the intra-domain routing protocol of the IPv6 network. Under this protocol, each router actively tests the link status of its adjacent routers and spreads the link status information in the area. Each router receives the link status information and builds a complete routing table. In this way, Each router has a complete link-state database. The IS-ISv6 dynamic routing protocol has the advantages of fast convergence speed, good stability, and easy expansion, and is widely used in domestic and foreign telecom operators' networks. [0003] For a network that uses the IS-IS...
