CCNA--LAB-2:配置RIP路由协议

CCNA--LAB-2:配置RIP路由协议
 
拓扑如上:
 
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)#no sh
R1(config-if)#exit
R1(config)#router rip     --进入并启用RIP配置模式
R1(config-router)#version 2     --指定版本2
R1(config-router)#no auto-summary     --不要自动汇总
R1(config-router)#network 12.1.1.0     --宣告直连的网段
R1(config-router)#network 192.168.1.0     --宣告直连的网段
R1(config-router)#end

查看路由表:
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是通过RIP路由学习到 192.168.2.0/24网段
 
 
 
 
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)#no sh
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 
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
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
 
验证在PC0上拼PC1:
 
PC>ping 192.168.2.1
Pinging 192.168.2.1 with 32 bytes of data:

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
 
总结:
RIP的工作原理在前面都有介绍,下面解释一下为什么要指定版本2(version 2),版本1与版本2最大的区别就是,2是以组播的方式发送更新,地址为224.0.0.9,且支持可变长子网掩码,而1是
广播的方式发送更新,且不支持变长子网掩码!
