CCNA--LAB-2:配置RIP路由協定

拓撲如上:

R1:

Router>en

Router#conf t

Router(config)#hostname R1

R1(config)#int

R1(config)#interface f0/0

R1(config-if)#ip address 192.168.1.254 255.255.255.0

R1(config-if)#no sh

R1(config-if)#int f0/1

R1(config-if)#ip add

R1(config-if)#ip address 12.1.1.1 255.255.255.0

R1(config-if)#exit

R1(config)#router rip     --進入并啟用RIP配置模式

R1(config-router)#version 2     --指定版本2

R1(config-router)#no auto-summary     --不要自動彙總

R1(config-router)#network 12.1.1.0     --宣告直連的網段

R1(config-router)#network 192.168.1.0     --宣告直連的網段

R1(config-router)#end

檢視路由表:

R1#show ip route 

Codes: C - connected, S - static, I - IGRP, 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, E - EGP

       i - IS-IS, 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

     12.0.0.0/24 is subnetted, 1 subnets

C       12.1.1.0 is directly connected, FastEthernet0/1

C    192.168.1.0/24 is directly connected, FastEthernet0/0

R    192.168.2.0/24 [120/1] via 12.1.1.2, 00:00:04, FastEthernet0/1     

                      R是通過RIP路由學習到 192.168.2.0/24網段

R2:

Router(config)#hostname R2

R2(config)#interface f0/1

R2(config-if)#ip address 12.1.1.2 255.255.255.0

R2(config-if)#no sh

R2(config)#interface f0/0

R2(config-if)#ip address 192.168.2.254 255.255.255.0

R2(config-if)#exit

R2(config)#router rip

R2(config-router)#version 2

R2(config-router)#no auto-summary 

R2(config-router)#network 192.168.2.0

R2(config-router)#network 12.1.1.0

R2(config-router)#end

R2#show ip route 

R    192.168.1.0/24 [120/1] via 12.1.1.1, 00:00:20, FastEthernet0/1

C    192.168.2.0/24 is directly connected, FastEthernet0/0

驗證在PC0上拼PC1:

PC>ping 192.168.2.1

Ping statistics for 192.168.2.1:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

    Minimum = 28ms, Maximum = 73ms, Average = 54ms

總結:

RIP的工作原理在前面都有介紹,下面解釋一下為什麼要指定版本2(version 2),版本1與版本2最大的差別就是,2是以多點傳播的方式發送更新,位址為224.0.0.9,且支援可變長子網路遮罩,而1是

廣播的方式發送更新,且不支援變長子網路遮罩!
