实验目的：

1、掌握RIPv1的基本配置。

2、掌握RIPv1的有类特性。

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RIPv1的配置，R1的配置如下：

R1(config)#router rip

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)#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)#network 13.0.0.0

R3(config-router)#network 23.0.0.0

R3(config-router)#network 3.0.0.0

R3(config-router)#exit

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

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route


Gateway of last resort is not set


     1.0.0.0/32 is subnetted, 1 subnets

C       1.1.1.1 is directly connected, Loopback1

R    2.0.0.0/8 [120/1] via 12.1.1.2, 00:00:01, FastEthernet0/0

R    3.0.0.0/8 [120/1] via 13.1.1.3, 00:00:07, FastEthernet1/0

R    23.0.0.0/8 [120/1] via 13.1.1.3, 00:00:07, FastEthernet1/0

                [120/1] via 12.1.1.2, 00:00:01, FastEthernet0/0 

     12.0.0.0/24 is subnetted, 1 subnets

C       12.1.1.0 is directly connected, FastEthernet0/0

     13.0.0.0/24 is subnetted, 1 subnets

C       13.1.1.0 is directly connected, FastEthernet1/0

此时看到路由表中出现“R”开头的路由条目，则为R1从R2和R3学习到的RIPv1路由，并且进行连通性测试，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

R1上测试成功，同样可以在R2和R3上进行测试，此实验完成。
