Method for realizing message retransmission under routing device

Abstract

The method includes following steps: the requirement response message is transmitted to all routes in the route table of route equipment, the route receiving the response message is determined; when the router equipment needs to retransmit message, the message will be retransmitted by route receiving the response message in the route table. The invention optimizes the route table according to the next jump network equipment.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing message forwarding in routing equipment. Background technique [0002] At present, the routing device determines the forwarding route of the received message according to the routing table, and forwards the received message according to the forwarding route. [0003] The routing table in the routing device is shown in Table 1: [0004] Table 1 [0005] Numbering Destination address mask Next hop out interface A 10.1.1.0 255.255.255.0 20.1.1.1 Ethernet1 / 0 / 0 B 10.1.0.0 255.255.0.0 30.1.1.1 Ethernet1 / 0 / 1 C 10.1.2.0 255.255.255.0 20.1.1.1 Ethernet1 / 0 / 0 D 10.1.2.0 255.255.255.0 30.1.1.1 Ethernet1 / 0 / 1 [0006] In the prior art, the routing device forwards the message according to the routing...

AI Technical Summary

Problems solved by technology

Because the packet forwarding method of general routers stipulates that the same data flow hits the same route, therefore, some network end users may not be able to access 10.1.2.1

[0015] In addition, dynamic routing protocols may be subject to malicious attacks, resulting in normal data not being forwarded normally

For example, in RIP (Routing Information Protocol), network end users may maliciously construct packets whose next hop does not have a routing protocol. After the routing table is matched, normal data will not be forwarded normally, thus affecting the business of network end users.
