Dynamic routing configuration

Experimental content ：

  experimental analysis ：

Subject requirements R1 and R2 There are two loopback routes , Need to be in 192.168.1.0/24 Divide down , This topology requires 4 Loops and 2 A straight chain circuit , Equal to six network segments .

Experimental process ：

IP Divide ：

R1 Summary network segment of two loops ：192.168.1.32/27

R2 Summary network segment of two loops ：192.168.1.64/27

R1 and R2 Link circuit network segment between two ：192.168.1.0/30

R2 and R3 Link circuit network segment between two ：192.168.1.4/30

 

  Next, start configuring the loop and interface IP

The next step is to announce （RIP At the announcement , Declare only primary network segments ）： 

[r1-rip-1]network 192.168.1.0
[r2-rip-1]network 192.168.1.0
[r3-rip-1]network 192.168.1.0

At present except 3.3.3.0/24 The network segment is not available , Other network segments have been reached throughout the network , The next step is to R3 Configure the default route , Only one source is needed in the dynamic routing protocol , So just give R3 A configuration default route .

[r3-rip-1]default-route originate

Basically, the whole network can be reached here , But to avoid loops, reduce the number of routing entries , To ensure the security of updates , You also need to summarize manually （ On the update source router , All updates are sent to the configuration on the interface ）

[r2]interface g0/0/0
[r2-GigabitEthernet0/0/0]rip summary-address 192.168.1.64 255.255.255.224

test

 

 

 

 

  The test passed , To achieve the purpose of the experiment, the whole network can reach , To ensure the security of updates , Reduce the number of routing entries , Avoid loops .
