关闭EIGRP路由自动汇总.docx

08级网络与开发方向实验报告CCNA7-03 EIGRP路由自动汇总姓名：张三 日期：2010-9-7实验名称：EIGRP路由自动汇总试验目标：u 了解EIGRP协议自动汇总功能。u 在类的边界自动汇总。u 在不连续的网络禁止自动汇总实验环境：任务：u 在以上路由器上配置EIGRP协议。u 在不连续的地址禁用路由汇总步骤：1.在网络中配置EIGRP协议1.1在Router5、2、0、1上Router(config)#route eigr 10Router(config-router)#network 172.16.0.01.2在Router4、3上Router(config)#route eigr 10Router(config-router)#network 172.16.0.0Router(config-router)#network 10.0.0.01.3在Router6上Router(config)#route eigr 10Router(config-router)#network 10.0.0.02.查看路由汇总结果2.1在Router6上查看路由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 routeGateway of last resort is not set 10.0.0.0/24 is subnetted, 2 subnetsC 10.0.0.0 is directly connected, Serial3/0C 10.0.1.0 is directly connected, Serial2/0D 172.16.0.0/16 90/20514560 via 10.0.0.1, 00:14:03, Serial3/0 90/20514560 via 10.0.1.2, 00:13:41, Serial2/0Router#路由器看到到172.16.0.0/16网段有两条可用路由。这是错误的汇总。2.2在Router6上测试到PC0的连接Router#ping 172.16.10.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 172.16.10.2, timeout is 2 seconds:.!.!Success rate is 40 percent (2/5), round-trip min/avg/max = 13/14/15 msRouter#ping 172.16.10.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 172.16.10.2, timeout is 2 seconds:.!.!.Success rate is 40 percent (2/5), round-trip min/avg/max = 14/16/19 ms发现丢包。这是因为错误的路由汇总造成的。3.关闭EIGRP的自动汇总3.1在所有的路由器上运行以下命令Router(config)#router e 10Router(config-router)#no auto-summary 关闭自动汇总Router(config-router)#3.2在Router6上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 routeGateway of last resort is not set 10.0.0.0/8 is variably subnetted, 3 subnets, 2 masksD 10.0.0.0/8 90/21024000 via 10.0.0.1, 00:01:20, Serial3/0 90/21024000 via 10.0.1.2, 00:01:03, Serial2/0C 10.0.0.0/24 is directly connected, Serial3/0C 10.0.1.0/24 is directly connected, Serial2/0 172.16.0.0/16 is variably subnetted, 11 subnets, 2 masksD 172.16.0.0/16 is a summary, 00:01:37, Null0D 172.16.0.0/24 90/22050560 via 10.0.1.2, 00:00:07, Serial2/0D 172.16.1.0/24 90/22048000 via 10.0.1.2, 00:00:28, Serial2/0D 172.16.2.0/24 90/21538560 via 10.0.1.2, 00:00:28, Serial2/0D 172.16.3.0/24 90/21536000 via 10.0.1.2, 00:00:45, Serial2/0D 172.16.4.0/24 90/21026560 via 10.0.1.2, 00:00:45, Serial2/0D 172.16.5.0/24 90/21024000 via 10.0.1.2, 00:01:03, Serial2/0D 172.16.6.0/24 90/20514560 via 10.0.1.2, 00:01:03, Serial2/0D 172.16.8.0/24 90/20514560 via 10.0.0.1, 00:01:20, Serial3/0D 172.16.9.0/24 90/21024000 via 10.0.0.1, 00:01:20, Serial3/0D 172.16.10.0/24 90/21026560 via 10.0.0.1, 00:01:20, Serial3/0Router#ping 172.16.0.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 172.16.0.2, timeout is 2 seconds:.!能够ping通172.16.0.0/24网段Success rate is 80 percent (4/5), round-trip min/avg/max = 17/23/27 msRouter#ping 172.16.10.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to
