CCNP路由实验---6、理解EIGRP的查询 ? 实验步骤： 1、配置各路由器的名称、相连接口IP地址，并且使用Ping命令确认各路由器的直连口的互通性。 R1配置： R1(config)#int fa0/0 R1(config-if)#ip add 192.138.1.1 255.255.255.0 R1(config-if)#no shut R1(config-if)#exit R1(config)#int s1/2 R1(config-if)#ip add 172.16.1.1 255.255.255.252 R1(config-if)#no shut R1(config-if)#exit R1(config)#int loop 1 R1(config-if)#ip add 10.1.1.1 255.255.255.0 R1(config-if)#exit R2、R3类似。 2、给三台路由器配置EGIRP协议，自治系统号为80。本次实验采用通配符掩码配置R1的回环口。 R1(config)#router eigrp 80 R1(config-router)#network 172.16.0.0 R1(config-router)#network 192.138.0.0 R1(config-router)#network 10.1.0.0 0.0.255.255 R2、R3同理配置好。 3、查看R1、R2与R3的路由表，确认EIGRP工作正常。 R1： R1#sh ip route Codes: 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 route ? Gateway of last resort is not set ? 172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks D 172.16.1.4/30 [90/2681856] via 172.16.1.2, 00:01:48, Serial1/2 D 172.16.0.0/16 is a summary, 00:02:48, Null0 C 172.16.1.0/30 is directly connected, Serial1/2 10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks C 10.1.1.0/24 is directly connected, Loopback1 D 10.0.0.0/8 is a summary, 00:02:48, Null0 C 192.138.1.0/24 is directly connected, FastEthernet0/0 R2： R2#sh ip route eigrp D 10.0.0.0/8 [90/2297856] via 172.16.1.1, 00:08:27, Serial1/0R3： R3#sh ip route eigrp 172.16.0.0/30 is subnetted, 2 subnets D 172.16.1.0 [90/2681856] via 172.16.1.5, 00:03:17, Serial1/2 D 10.0.0.0/8 [90/2809856] via 172.16.1.5, 00:03:17, Serial1/2 4、在R2路由器上使用debug命令跟踪EIGRP的更新。 R2#debug eigrp fsm EIGRP FSM Events/Actions debugg
