Embodiment Construction

[0012] In the prior art, EIGRP and RIP are used for hybrid networking, and after the mutual redistribution of the two routing protocols is enabled, when there is multi-point redistribution in the network, some paths may be reachable but the path is not optimal Path, that is, the suboptimal routing problem that people often say, and in some cases, routing loop phenomenon, that is, the routing loop problem that people often say, may also occur, thereby affecting service performance or causing communication interruption.

[0013] The optimization method of EIGRP and RIP hybrid networking proposed by the present invention also needs to construct EIGRP and RIP hybrid network through multiple EIGRP routing domains and multiple RIP routing domains, but it is different from the prior art in that: in EIGRP In the routing domain and RIP routing domain, the bandwidth and delay parameter values ​​of the EIGRP and RIP routing protocols are uniformly formulated according to the interface att...

Abstract

The invention discloses an optimization method for EIGRP and RIP hybrid networking. The optimization method comprises the steps that in the process of building an EIGRP and RIP hybrid network through a plurality of EIGRP routing domains and a plurality of RIP routing domains, the bandwidth and delay parameter values of an EIGRP and RIP routing protocol are formulated according to the attribute of an interface; the bandwidth, delay and the hop count are carried in protocol messages of an EIGRP and an RIP and are transmitted in a link; after the EIGRP or the RIP receives respective protocol messages from the link, the measurement of each path is calculated through the same composite measurement calculation formula in the path selection process, and is adopted as the optimal judgment basis; change paths are transferred in a router adjacent to the EIGRP routing domains and the RIP routing domains. The optimization method has the advantages that the method is simple, the message type is not increased, and the problem of suboptimal routers and rooting loops caused by multi-point routing redistribution in EIGRP and RIP hybrid networking can be solved.

Description

technical field [0001] The invention relates to the field of routing protocols, in particular to the applicability technology of EIGRP and RIP routing protocols. Background technique [0002] With the rapid development of the network, the network structure and scale are becoming increasingly complex and large. It is very common for multiple routing protocols such as EIGRP and RIP to exist in the network. However, due to the protocol differences between EIGRP and RIP, the mixed network It is limited by the suboptimal routing and routing loop problems of multipoint redistribution. This requires finding a solution in the mixed networking of EIGRP and RIP. Contents of the invention [0003] The invention discloses an optimization method for EIGRP and RIP hybrid networking. The optimization method is to uniformly formulate EIGRP and RIP routing protocols according to interface attributes in the construction of EIGRP and RIP hybrid networks in multiple EIGRP routing domains and...
