2 网络拓扑
3 基本配置步骤
试验环境应经将路由器的所有接口和计算机的Ip地址已经按着网络拓扑配置。
只需在路由器上添加静态路由表即可。
3.1 在Router2上
1 Router#show ip route 查看现有的路由表,发现只有直连的网段的路由信息 2 Router#config t 3 Router(config)#ip route 172.16.1.0 255.255.255.0 172.16.3.2 4 Router(config)#ip route 172.16.4.0 255.255.255.0 172.16.3.2 5 Router(config)#ip route 172.16.5.0 255.255.255.0 172.16.3.2 6 Router(config)#ip route 172.16.2.0 255.255.255.0 172.16.3.2 7 Router#show ip route 8 Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP 9 D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 10 N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 11 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP 12 i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area 13 * - candidate default, U - per-user static route, o - ODR 14 P - periodic downloaded static route 15 Gateway of last resort is not set 16 172.16.0.0/24 is subnetted, 6 subnets 17 C 172.16.0.0 is directly connected, FastEthernet0/0 C 直连的网络 18 S 172.16.1.0 [1/0] via 172.16.3.2 S 添加的静态路由 19 S 172.16.2.0 [1/0] via 172.16.3.2 20 C 172.16.3.0 is directly connected, Serial2/0 21 S 172.16.4.0 [1/0] via 172.16.3.2 22 S 172.16.5.0 [1/0] via 172.16.3.2 23 Router#copy running-config startup-config 24 Destination filename [startup-config]? 25 Building configuration... 26 [OK]
