Abstract

The invention relates to the network communication field, and provides an IGP routing method and a device thereof for solving the defect in the prior art that group characters can not be used in an IGP protocol. The method comprises: collocating the group characters for first routing information of an IGP routing unit of a network device A, sending the first routing information to the IGP routing unit of a network device B by the IGP routing unit of the network device A, guiding the first routing information into a routing table of the network device B, guiding second routing information of the IGP routing unit of the network device A into a BGP routing unit of the network device A, sending the second routing information to the BGP routing unit of the network device B, matching the second routing information of the network device B with the first routing information of the network device B, and guiding the second routing information into the routing table of the network device B. The IGP routing method and the device thereof have the beneficial effects that the complexity of routing management can be effectively simplified, and low cost can be realized.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to the network security related field, and specifically to an IGP routing method and device. Background technique [0002] Interior Gateway Routing Protocol (IGP: Interior Gateway Protocol) is defined as a routing protocol used within an autonomous system. The function of the IGP routing protocol is to complete the routing of data packets in an autonomous system (AS: Autonomous System), or in other words, to tell how data packets are forwarded within the AS. RIP (Routing Information Protocol) and Open Shortest Path First (OSPF) are typical IGP routing protocols. [0003] Exterior Gateway Routing Protocol (EGP: Exterior Gateway Protocol) is defined as a routing protocol used between multiple autonomous systems. It mainly completes the routing of data packets between ASs, or in other words, tells which AS the data packets need to pass through in order to reach the destinatio...
