实验目的:

1、掌握RIPv2的基本配置。

2、掌握RIPv2的无类特性。

实验拓扑:

实验步骤:

1、依据图中拓扑配置各设备的IP地址,并保证直连连通性;

在R1上做如下配置:

R1(config)#int f0/0

R1(config-if)#no shutdown

R1(config-if)#ip address 12.1.1.1 255.255.255.0

R1(config-if)#exit

R1(config)#int f1/0

R1(config-if)#no shutdown

R1(config-if)#ip address 13.1.1.1 255.255.255.0

R1(config-if)#exit

R1(config)#int loopback 1

R1(config-if)#ip address 1.1.1.1 255.255.255.255

R1(config-if)#exit

在R2上做如下配置:

R2(config)#int f0/0

R2(config-if)#no shutdown

R2(config-if)#ip address 12.1.1.2 255.255.255.0

R2(config-if)#exit

R2(config)#int f1/0

R2(config-if)#no shutdown

R2(config-if)#ip address 23.1.1.2 255.255.255.0

R2(config-if)#exit

R2(config)#int loopback 1

R2(config-if)#ip address 2.2.2.2 255.255.255.255

R2(config-if)#exit

在R3上做如下配置:

R3(config)#int f0/0

R3(config-if)#no shutdown

R3(config-if)#ip address 13.1.1.3 255.255.255.0

R3(config-if)#exit

R3(config-if)#int f1/0

R3(config-if)#no shutdown

R3(config-if)#ip address 23.1.1.3 255.255.255.0

R3(config-if)#exit

R3(config)#int loopback 1

R3(config-if)#ip address 3.3.3.3 255.255.255.255

R3(config-if)#exit

在其中一台路由器上进行连通性测试:

 

R1#ping 12.1.1.2

 

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 12.1.1.2, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 20/34/48 ms

R1#ping 13.1.1.3

 

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 13.1.1.3, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 16/31/48 ms

此时说明直连连接没有问题。

2.在每台路由器开始进行RIPv2的配置,R1的配置如下:

R1(config)#router rip

R1(config-router)#version 2 

R1(config-router)#no auto-summary 

R1(config-router)#network 12.0.0.0 

R1(config-router)#network 13.0.0.0

R1(config-router)#network 1.0.0.0

R1(config-router)#exit

R2的配置如下:

R2(config)#router rip

R2(config-router)#version 2

R2(config-router)#no auto-summary

R2(config-router)#network 12.0.0.0

R2(config-router)#network 23.0.0.0

R2(config-router)#network 2.0.0.0

R2(config-router)#exit

R3的配置如下:

R3(config)#router rip

R3(config-router)#version 2

R3(config-router)#no auto-summary

R3(config-router)#network 13.0.0.0

R3(config-router)#network 23.0.0.0

R3(config-router)#network 3.0.0.0

R3(config-router)#exi

3.在任意一台路由器上查看路由表并进行测试:

在R1上查看路由表:

R1#show ip route rip 

     2.0.0.0/32 is subnetted, 1 subnets

R       2.2.2.2 [120/1] via 12.1.1.2, 00:00:04, FastEthernet0/0

     3.0.0.0/32 is subnetted, 1 subnets

R       3.3.3.3 [120/1] via 13.1.1.3, 00:00:12, FastEthernet1/0

     23.0.0.0/24 is subnetted, 1 subnets

R       23.1.1.0 [120/1] via 13.1.1.3, 00:00:12, FastEthernet1/0

                [120/1] via 12.1.1.2, 00:00:04, FastEthernet0/0

可以看到R1从R2和R3学习到的RIPv2路由,此时进行连通性测试,如下:

R1#ping 2.2.2.2 source 1.1.1.1


Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:

Packet sent with a source address of 1.1.1.1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/24/44 ms

R1#ping 3.3.3.3 source 1.1.1.1


Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:

Packet sent with a source address of 1.1.1.1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 16/24/40 ms

此时R1上测试成功,同样方法可以在R2和R3上测试成功,表明通过RIPv2使得三台路由器的环回网段都相互连通,此实验完成。
