-----------------------------------------------------------------------------------------------
第一步：基本IP通讯！
R1>en
R1#conf t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int s0/0 R1(config-if)#ip add 192.168.12.1 255.255.255.0 R1(config-if)#clock rate 64000 R1(config-if)#no sh R1(config-if)#exit R1(config)#int s0/1 R1(config-if)#ip add 192.168.13.1 255.255.255.0 R1(config-if)#clock rate 64000 R1(config-if)#no sh R1(config-if)#exit R1(config)#int lo 0 R1(config-if)#ip add 1.1.1.1 255.255.255.0 R1(config-if)#exit R1(config)#------------------------------------------------------------------------------------------------
R2>en R2#conf t Enter configuration commands, one per line. End with CNTL/Z. R2(config)#int s0/0 R2(config-if)#ip add 192.168.12.2 255.255.255.0 R2(config-if)#no sh R2(config-if)#exit R2(config)#int lo 0 R2(config-if)#ip add 2.2.2.2 255.255.255.0 R2(config-if)#exit R2(config)#------------------------------------------------------------------------------------------------
R3>en
R3#conf t Enter configuration commands, one per line. End with CNTL/Z. R3(config)#int s0/1 R3(config-if)#ip add 192.168.13.3 255.255.255.0 R3(config-if)#no sh R3(config-if)#exit R3(config)#int lo 0 R3(config-if)#ip add 3.3.3.3 255.255.255.0 R3(config-if)#exit R3(config)#------------------------------------------------------------------------------------------------
第二步：EIGRP宣告路由！
R1(config)#router eigrp 10 -------10代表AS号，所有必须一致，否则学习不到路由信息的！R1(config-router)#no au ----------关闭自动汇总R1(config-router)#net 192.168.12.0
R1(config-router)#net 192.168.13.0 R1(config-router)#net 1.1.1.0 R1(config-router)#end R1#-------------------------------------------------------------------------------------------------
R2(config)#router eigrp 10 R2(config-router)#no au R2(config-router)#net 192.168.12.0 R2(config-router)#net 2.2.2.0 R2(config-router)#end R2#-------------------------------------------------------------------------------------------------
R3(config)#router eigrp 10 R3(config-router)#net 192.168.13.0 R3(config-router)#net 3.3.3.0 R3(config-router)#end R3#-------------------------------------------------------------------------------------------------
第三步：查看路由表！
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 routeGateway of last resort is not set
C 192.168.12.0/24 is directly connected, Serial0/0
1.0.0.0/24 is subnetted, 1 subnets C 1.1.1.0 is directly connected, Loopback0 C 192.168.13.0/24 is directly connected, Serial0/1 2.0.0.0/24 is subnetted, 1 subnets D 2.2.2.0 [90/2297856] via 192.168.12.2, 00:03:51, Serial0/0 D 3.0.0.0/8 [90/2297856] via 192.168.13.3, 00:03:30, Serial0/1 R1#-------------------------------------------------------------------------------------------------
R2#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 routeGateway of last resort is not set

1.0.0.0/24 is subnetted, 1 subnets D 1.1.1.0 [90/2297856] via 192.168.12.1, 00:03:58, Serial0/0 D 192.168.13.0/24 [90/2681856] via 192.168.12.1, 00:03:58, Serial0/0 2.0.0.0/24 is subnetted, 1 subnets C 2.2.2.0 is directly connected, Loopback0 D 3.0.0.0/8 [90/2809856] via 192.168.12.1, 00:03:35, Serial0/0 R2#-------------------------------------------------------------------------------------------------
R3#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 routeGateway of last resort is not set
D 192.168.12.0/24 [90/2681856] via 192.168.13.1, 00:03:42, Serial0/1
1.0.0.0/24 is subnetted, 1 subnets D 1.1.1.0 [90/2297856] via 192.168.13.1, 00:03:42, Serial0/1 C 192.168.13.0/24 is directly connected, Serial0/1 2.0.0.0/24 is subnetted, 1 subnets D 2.2.2.0 [90/2809856] via 192.168.13.1, 00:03:42, Serial0/1 3.0.0.0/8 is variably subnetted, 2 subnets, 2 masks C 3.3.3.0/24 is directly connected, Loopback0 D 3.0.0.0/8 is a summary, 00:03:39, Null0 R3#-------------------------------------------------------------------------------------------------
第四步：查看EIGRP邻居！
R1#sh ip eigrp neighbors
IP-EIGRP neighbors for process 10 H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 1 192.168.13.3 Se0/1 13 00:05:20 100 600 0 3 0 192.168.12.2 Se0/0 11 00:05:42 55 330 0 4 R1#-------------------------------------------------------------------------------------------------
R2#sh ip eigrp neighbors IP-EIGRP neighbors for process 10 H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 192.168.12.1 Se0/0 12 00:05:31 56 336 0 5 R2#-------------------------------------------------------------------------------------------------
R3#sh ip eigrp neighbors IP-EIGRP neighbors for process 10 H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 192.168.13.1 Se0/1 12 00:05:03 460 2760 0 4 R3#------------------------------------------------------------------------------------------------
第五步：ping测试！
R3#ping 1.1.1.1 source 3.3.3.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds: Packet sent with a source address of 3.3.3.3 !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 24/37/48 ms R3#-------------------------------------------------------------------------------------------------
R3#ping 2.2.2.2 source 3.3.3.3Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds: Packet sent with a source address of 3.3.3.3 !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 16/28/56 ms R3#-------------------------------------------------------------------------------------------------
好了，本教程也就此告一段落！我们的学习是一个循序渐进的过程！可能有的朋友会说这里面还有许多知识没涉及到啊！
我打算将在后面再为朋友们献上，等大家都有一定的基础的时候，那个时候学习起来会轻松多了！谢谢……
