2.4 RIPv1基本配置

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:

PingingLab传世经典系列《CCNA完全配置宝典》-2.4 RIPv1基本配置_思科认证

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[j1]

R1(config-router)#network 12.0.0.0[j2]

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[j3]

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[j4]

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。  


[j1]进入RIP进程,默认为RIPv1

[j2]注意,此处network是用于宣告主类网络号,不需要具体的路由条目如12.1.1.0,也不需要路由掩码。

[j3]RIPv1是20世纪70年代所开发的,是一种古老的路由协议,所以呈现有类特性-路由更新不夹带掩码并且自动汇总。此处2.2.2.2/32自动汇总为2.0.0.0/8,3.3.3.3/32则自动汇总为3.0.0.0/8

[j4]带源PING通,表示对方路由器也能PING通本地环回接口。
