The simple application of rip, it is hoped that this will make it easier for colleagues in operation and maintenance.

Experimental topology diagram:

Lab requirements:

When there are many routers or multilayer switches in the intranet, it is necessary to configure dynamic routing for communication between different network segments. For example, manual configuration is time-consuming and error-prone. You can choose to use rip (routing Information Protocol) to automatically synchronize routing entries between different routers.

Configure rip between different routers to realize pc interworking

The steps of the experiment:

Configure the corresponding port with ip address as shown in the topology diagram. Configure rip on the router:

[Huawei-rip-1] network 192.168.3.0

[Huawei-rip-1] network 192.168.4.0

Other routers have the same configuration verification, testing

Summary of experiment

In Rip, network is the directly connected network segment of the route.

In the IGP protocol, the role of network is:

For example, network 192.168.3.0, 192.168.3.0 represents a network range, and routing protocol processes are enabled on devices that are covered by the range indicated by 192.168.3.0:

1. Protocol messages can be sent on this port

2. You can receive protocol messages on this port

3. You can put the network part of the IP address on the port into the protocol message, which is generally used in small-scale enterprise internal networks.

(because RIP has a maximum hop limit of 16 hops)

Popularize the knowledge about rip:

Principle:

1. After the router enables RIP, it will declare the entries in its local routing table to RIP.

2. Send these update entries on the port that starts the RIP protocol

3. After the other RIP router receives it, after route comparison, put the best entries into the routing table.

4. All RIP routers update their routing tables periodically and broadcast.

(in RIPv2, it is triggered, incremental, and multicasting.)

(RIP neighbor table): all routers that can communicate with themselves are called RIP neighbors.

RIP database: contains locally declared route entries and route entries learned from other routers

RIP routing table: represents the best route selected from the database

I hope it will be helpful to everyone!
