配置路由器Router1 Press Enter to Start Router> Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname Router1 Router1(config)#interface ethernet 0 Router1(config-if)#ip address 192.168.1.1 255.255.255.0 Router1(config-if)#no shutdown %LINK-3-UPDOWN: Interface Ethernet0, changed state to up Router1(config-if)#interface serial 0 Router1(config-if)#encapsulation hdlc Router1(config-if)#ip address 192.168.2.1 255.255.255.0 Router1(config-if)#no shutdown %LINK-3-UPDOWN: Interface Ethernet0, changed state to up %LINK-3-UPDOWN: Interface Ethernet0, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down Router1(config-if)# 同理配置路由器Router2、Router3。 配置2台PC 用ipconfig命令配置PC1和PC2，如图所示。
路由器Router1的路由表信息 Router1#show ip route Codes: C – connected, S – static, I – IGRP, R – RIP, M – mobile, B – BGP D – EIGRP, EX – EIGRP external, 0 – 0SPF, IA – OSPE inter area E1 – OSPE external type 1, E2 – OSPE external type 2, E – EGP i – IS-IS, L1 – IS-IS level-1, L2 – IS-IS level-2, * – candidate default U – per-user static route Gateway of last resort is not set C 192.168.1.0/24 is directly connected, Ethernet0 C 192.168.2.0/24 is directly connected, Serial0 可以看到，路由器Router1只有两个直连路由分别到达网络192.168.1.0和192.168.2.0，没有到达网络192.168.3.0和192.168.4.0的路由，所以，在Router1上ping网络192.168.3.0和192.168.4.0是ping不通的。 同样，路由器Router2只有两个直连路由分别到达网络192.168.2.0和192.168.3.0，没有到达网络192.168.1.0和192.168.4.0的路由，所以，在Router2上ping网络192.168.1.0和192.168.4.0是ping不通的。 为了能够使非直连的网络可以互通，可以通过手工配置的方法来添加静态路由。 4．配置静态路由 配置Router1到网络192.168.3.0和192.168.4.0的静态路由 Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2 Router1(config)#ip route 192.168.4.0 255.255.255.0 192.168.2.2 Router1(config)# 5．再次查看路由表信息 查看路由器Router1的路由表信息 Router1#show ip route 6．再次测试PC1和PC2之间的连通性 可以看到，PC2可以ping通PC1，这表明PC1和PC2之间的3个路由器配置的静态路由在发挥作用。 C:>ping 192.168.1.2 7．再次查看路由器的配置 可以通过show running-config命令再次查看各个路由器的配置信息。 （2）动态路由RIP配置 动态路由RIP拓扑图
配置路由器Router1的各个接口及其OSPF协议 Router> Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z.

2．利用show running-config命令来显示各个路由器的配置信息
路由器Router1的配置信息 Router1#show running-config 3．利用show ip route命令来查看各个路由器的路由表信息 查看路由器Router1的路由表信息 Router1#show ip route 4．测试各个路由器接口的连通性 以路由器Router1为例，与路由器Router1非直接相连的有9个对应的接口IP地址，可以用ping命令测试其连通性。如果ping通，表明路由已经生效。 5．查看邻居路由信息 查看路由器Router1的邻居路由信息 Router1#show ip ospf neighbor 6．查看路由器上直接连接的端口信息 查看路由器Router1上直接连接的端口信息 Router1#show ip ospf interface 三、实验内容 1、Boson Netsim的安装 2、静态路由配置 3、动态路由RIP/OSPF配置 四、实验设备 1、计算机 2、局域网络 3、Boson Netsim软件
