这次介绍的是使用思科模拟器来完成静态路由、动态路由和RIP配置的具体方法。其中,动态路由协议和RIP的命令就两行比较简单。组网方式是三台cisco路由器连成线(分别为Router1、Router2和Router3),R1和R3分别有联了PC1和PC2客户端并要实现相互的通信,具体的ip地址和网段设置参加下图所示。
本次实验拓扑图如下:
要想实现pc1和pc2通讯,就要对R1、R2和R3进行如下配置:
1. 静态配置命令格式如下:
对于R1
Router>en
Router#conf
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2
ip route +目的网段+目的网段的子网掩码+下一跳IP
查看配置情况 特权模式下 Router#show ip route
其他的路由同理配置。
2. RIP 动态路由配置命令 network +相邻网段
Router#config
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#router rip
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.2.0
Router#write
Building configuration...
[OK]
查看命令
Router#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
C 192.168.1.0/24 is directly connected, FastEthernet0/0
C 192.168.2.0/24 is directly connected, FastEthernet0/1
S 192.168.3.0/24 [1/0] via 192.168.2.2
R 192.168.4.0/24 [120/2] via 192.168.2.2, 00:00:19, FastEthernet0/1
3.查看pc 互ping的情况
注意:在做的时候,动态配置的时候,只有全部路由都配置好以后,在查看的时候才能显示出来。
