Rip configuration instance learning record

RIP Configure the instance

Routing information protocol RIP（Routing Information Protocol） It is a routing protocol based on distance vector algorithm , Using the number of jumps as the measurement standard . because 15 Jump to maximum , therefore RIP It can only be applied to small-scale networks , Such as campus network and other regional networks with relatively simple structure ;

1、 The goal of the experiment

adopt RIP Configuration of to realize network interworking

2、 Network topology

notes ：PC Of IP Address 、 Subnet mask and gateway , Click on PC Enter self configuration

3、 Configuration steps

（1） Configure ports by topology IP Address

R1：

<Huawei>system-view  // Enter the system view 
[Huawei]sysname R1  // Rename the device 
[R1]interface GigabitEthernet0/0/1
[R1-GigabitEthernet0/0/1]ip address 20.1.1.1 24  // configure port  IP  Address 
[R1-GigabitEthernet0/0/1]quit	
[R1]interface GigabitEthernet0/0/0
[R1-GigabitEthernet0/0/0]ip address 10.1.1.1 24  // configure port  IP  Address 
[R1-GigabitEthernet0/0/0]quit

R2：

<Huawei>system-view  // Enter the system view 
[Huawei]sysname R2  // Rename the device 
[R2]interface GigabitEthernet0/0/1
[R2-GigabitEthernet0/0/1]ip address 30.1.1.1 24  // configure port  IP  Address 
[R2-GigabitEthernet0/0/1]quit	
[R2]interface GigabitEthernet0/0/0
[R2-GigabitEthernet0/0/0]ip address 10.1.1.2 24  // configure port  IP  Address 
[R2-GigabitEthernet0/0/0]quit

（2） start-up RIP And enable in the specified network segment RIP

notes ： Use network Command enable RIP The network address of , It must be the address of the natural network segment . Otherwise there will be mistakes ：(Error: The network address is invalid, and the specified address must be major-net address without any subnets.) Simply speaking , You just need to enter the main class network address of the interface . example ： To configure R1 when , Out of commission network 10.1.1.0 , And should be used network 10.0.0.0 , because 10.1.1.1 The main class address of is 10.0.0.0; Another example 192.168.10.1 The main class address of is 192.168.10.0

R1：

[R1]rip 1  // start-up  RIP 
[R1-rip-1]version 2  // Specify Global RIP edition 
[R1-rip-1]network 20.0.0.0  // Enable... In the specified network segment RIP 
[R1-rip-1]network 10.0.0.0  // Enable... In the specified network segment RIP 
[R1-rip-1]quit

R2：

[R2]rip 1  // start-up  RIP 
[R2-rip-1]version 2  // Specify Global RIP edition  
[R2-rip-1]network 10.0.0.0  // Enable... In the specified network segment RIP 
[R2-rip-1]network 30.0.0.0  // Enable... In the specified network segment RIP 
[R2-rip-1]quit

4、 test

（1） View routing table

R1：

[R1]display ip routing-table  // View routing table

（2） Test connectivity

use PC1 Go to ping PC2 Of IP Address , Found that it has been connected

use PC2 Go to ping PC1 It can also be connected

5、 Summary

RIP It is mainly used when updating and maintaining routing information 4 A timer ： Update timer 、 Aging timer 、 Garbage collection timer 、 Inhibit timer .

RIPv1 and RIPv2 The main difference ：
RIPv1 It's a classed routing protocol ;RIPv1 Can not support VLSM, The protocol message does not carry mask information , Manual summary is not supported , It only supports publishing protocol messages by broadcasting ;

RIPv2 It's a classless routing protocol ;RIPv2 Can support VLSM, The protocol message carries mask information , Manual summary is supported , Support plaintext authentication and MD5 authentication , It supports sending messages in the form of broadcast or multicast ;

RIP Routing disadvantages ：
because 15 Jump to maximum , therefore RIP It can only be applied to small-scale networks ; Slow convergence ; The route selected according to the number of hops , Not necessarily the best route .

When the network fails or the network topology changes ,RIP The network may generate routing loops . You can pass the maximum number of hops 、 Horizontal segmentation 、 Toxicity reversal 、 Trigger update 、 Suppression time and other technologies to avoid the generation of loops .
