实验6 静态路由和默认路由 实验目的 通过本实验，需要掌握以下技能：1) 路由表的概念2) IP route 命令的使用3) 根据需求正确配置静态路由4) 根据需求使用默认路由 拓扑结构 实现1.1.1.0/24, 2.2.2.0/24, 3.3.3.0/24网络之间能互相通信 实验步骤n 步骤1：在各路由器上配置IP 地址、保证直连链路的连通性R2(config)#int loopback0 R2(config-if)#ip address 2.2.2.2 255.255.255.0 R2(config)#int s1/0 R2(config-if)#ip address 12.1.1.2 255.255.255.0 R2(config-if)#no shutdown R1(config)#int loopback0 R1(config-if)#ip address 1.1.1.1 255.255.255.0 R1(config)#int s1/0 R1(config-if)#clock rate 64000R1(config-if)#ip address 12.1.1.1 255.255.255.0 R1(config-if)#no shutdown R1(config)#int s1/1 R1(config-if)#clock rate 64000R1(config-if)#ip address 13.1.1.1 255.255.255.0 R1(config-if)#no shutdown R3(config)#int loopback0 R3(config-if)#ip address 3.3.3.3 255.255.255.0 R3(config)#int s1/1 R3(config-if)#ip address 13.1.1.3 255.255.255.0 R3(config-if)#no shutdown n 步骤2：R2 上配置静态路由R2(config)#ip route 1.1.1.0 255.255.255.0 s1/0/ 下一跳为接口形式，s1/0是点到点的链路，注意应该是R2上的s1/0R2(config)#ip route 3.3.3.0 255.255.255.0 12.1.1.1/ 下一跳为IP地址形式，12.1.1.1是R1上的IP地址n 步骤3：R1 上配置静态路由R1(config)#ip route 2.2.2.0 255.255.255.0 s1/0R1(config)#ip route 3.3.3.0 255.255.255.0 s1/1 n 步骤4：R3 上配置静态路由R3(config)#ip route 1.1.1.0 255.255.255.0 s1/1R3(config)#ip route 2.2.2.0 255.255.255.0 s1/1 实验调试n 在R2,R1,R3上查看路由表 R2#show ip routeCodes: C - connected, S - static, 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 i - IS-IS, su - IS-IS summary, 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 routeGateway of last resort is not set 1.0.0.0/24 is subnetted, 1 subnetsS 1.1.1.0 is directly connected, Serial1/0 2.0.0.0/24 is subnetted, 1 subnetsC 2.2.2.0 is directly connected, Loopback0 3.0.0.0/24 is subnetted, 1 subnetsS 3.3.3.0 1/0 via 12.1.1.1 12.0.0.0/24 is subnetted, 1 subnetsC 12.1.1.0 is directly connected, Serial1/0R1#show ip routeCodes: C - connected, S - static, 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 i - IS-IS, su - IS-IS summary, 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 routeGateway of last resort is not set 1.0.0.0/24 is subnetted, 1 subnetsC 1.1.1.0 is directly connected, Loopback0 2.0.0.0/24 is subnetted, 1 subnetsS 2.2.2.0 is directly connected, Serial1/0 3.0.0.0/24 is subnetted, 1 subnetsS 3.3.3.0 is directly connected, Serial1/1 12.0.0.0/24 is subnetted, 1 subnetsC 12.1.1.0 is directly connected, Serial1/0 13.0.0.0/24 is subnetted, 1 subnetsC 13.1.1.0 is directly connected, Serial1/1R3#show ip routeCodes: C - connected, S - static, 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 i - IS-IS, su - IS-IS summary, 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 routeGateway of last resort is not set 1.0.0.0/24 is subnetted, 1 subnetsS 1.1.1.0 is directly connected, Serial1/1 2.0.0.0/24 is subnetted, 1 subnetsS 2.2.2.0 is directly connected, Serial1/1 3.0.0.0/24 is subnetted, 1 subnetsC 3.3.3.0 is directly connected, Loopback0 13.0.0.0/24 is subnetted, 1 subnetsC 13.1.1.0 is directly connected, Serial1/1n 在各路由器上ping其它路由器的环回口R2#ping 1.1.1.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:!Success rate is 100 percent (5/5), round-trip min/avg/max = 4/20/60 ms R2#ping 3.3.3.3Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:.Success rate is 0 percent (0/5)R2#ping 3.3.3.3 source 2.2.2.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:Packet sent with a source address of 2.2.2.2 !Success rate is 100 percent (5/5), round-trip min/avg/max = 12/44/92 ms【实验结论】1) 各路由器上ping loopback地址所在的直连网段都能通2) R1上ping 2.2.2.2和3.3.3.3都能通3) R2上ping 3.3.3.3和R3上ping 2.2.2.2是不通的，但R2
