HCIA_ Rip experiment

The experimental requirements

1、R3 Loopback is 3.3.3.0/24
2、 The other is based on 192.168.1.0/24 division
3、r1/2 There are two loops
4、 The whole network runs RIPV2, But you can't directly declare R3 The loopback of
5、 Network wide accessibility , To ensure the security of updates , Reduce the number of routing entries , Avoid loops

The topology

The analysis process

Address partition ：
192.168.1.0/24
192.168.1.0/26
192.168.1.0/27
192.168.1.32/27

192.168.1.64/26
192.168.1.64/27
192.168.1.96/27

192.168.1.128/26
192.168.1.128/30
192.168.1.132/30

192.168.1.192/26

stay R1、R2、R3 Up operation RIPV2 agreement , And declare for network segment
about R3 The loopback above sets the default route
Then the route summary of the response
stay R1 And R2 Make an encryption between ,R2 And R3 And then do a kind of encryption
