Embodiment 1

[0028] figure 1 It is a flow chart of the method for controlling the generation of routing update messages provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the method for controlling the generation of the routing update message in this embodiment includes:

[0029] Step 1, the network device monitors the routing status of the network;

[0030] Wherein, the network is composed of multiple network devices configured with the RIP routing protocol, and the network device usually refers to a device with a routing function, usually a router. In step 1, the network device monitors the routing status of the network where it is located, that is, monitors the routing information between various network devices on the network where it is located. The network device may detect that the routing information of the network is changing. For example, it may detect that a port is active (UP) or a port is invalid (Down), or it may detect that a network device j...

Embodiment 2

[0038] figure 2 It is a flow chart of the method for controlling the generation of routing update messages provided by Embodiment 2 of the present invention. The execution subject of this embodiment is each network device in the network, and this embodiment can be realized based on Embodiment 1, such as figure 2 As shown, the method of the present embodiment includes the following steps:

[0039] Step 101, when the network device monitors that the route of the network is in a converged state, it sends a connection request to the network monitor in the network to establish a connection with the network monitor;

[0040] Specifically, the process for the network device to monitor the routing state of the network can be found in the description in Embodiment 1, and will not be repeated here. In a network formed by multiple network devices configured with the RIP routing protocol, when the network routes converge (that is, the routing table information of each network device do...

Embodiment 3

[0061] image 3 The flow chart of the method for controlling the generation of routing update messages provided by Embodiment 3 of the present invention, this embodiment can be implemented based on the above-mentioned Embodiment 1 or Embodiment 2, such as image 3 As shown, the method for controlling routing message generation in this embodiment includes the following steps:

[0062] Step 200, the whole network is started, that is, each router (comprising the network monitor) starts its own RIP routing protocol, and when each router is in the ready state, execute step 201;

[0063] Step 201, each router in the network judges whether the routing of the network is convergent;

[0064] Specifically, in the RIP network, all routers that enable the RIP routing protocol enable the UT suppression function through configuration commands. The router with the UT suppression function enabled takes each UT as an interval to monitor whether there is any change in its own routing table. ...

Abstract

The invention provides a method for controlling generation of routing update message and network equipment thereof. The method comprises the steps that the network equipment can be used for monitoring the route state of a network; when the network equipment monitor that a route of the network is in a converged state, the set time of a local route information update timer is preset into update timing time; and then, timing is started again for inhibiting the generation of sending route update message. By adopting the method for controlling generation of routing update message and the network equipment thereof, when the network equipment monitor that the route of the network is in a converged state, the timing time of the local route information update timer is set into update timing time, and timing is started again before timing is finished, so that the routing update message is inhibited to be generated and sent, the impact and the waste of network bandwidth for the network equipment caused by sending a great deal of routing update message can be reduced, and the cost of the routing update message is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and network equipment for controlling generation of routing update messages. Background technique [0002] Routing Information Protocol (Routing Information Protocol, RIP for short) is a routing protocol widely used in small networks. The RIP routing protocol adopts the distance vector algorithm and is a distance vector protocol. The RIP routing protocol uses timers to control the updating of routing information. In the RIP routing protocol, there are four commonly used timers, namely the RIP routing information update timer (Update Timer; abbreviated as: UT), the routing information timeout invalidation timer (Invalid Timer; abbreviated as: IT), and the hold timer. A Holddown Timer (abbreviated as: HT) and a failure routing information clearing timer (Flush Timer; abbreviated as: FT). [0003] Among them, the UT is used for the RIP router to periodicall...
