2：配置EIGRP
R1(config-if)#do show ip inter bri
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 192.168.12.1 YES manual up up
Serial1/0 unassigned YES unset administratively down down
Serial1/1 unassigned YES unset administratively down down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
Loopback0 10.1.0.1 YES manual up up
Loopback1 10.1.1.1 YES manual up up
R1(config-if)#do ping 192.168.12.2
Typeescape sequence to abort.
Sending5, 100-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds:
.!!!!
Successrate is 80 percent (4/5), round-trip min/avg/max = 80/127/152 ms
R1(config)#routereigrp 100
R1(config-router)#noauto-summary
R1(config-router)#network192.168.12.0
R1(config-router)#network10.0.0.0
R1(config)#routereigrp 100
R1(config-router)#nonet 10.0.0.0
R1(config-router)#net10.1.0.0
R1(config-router)#
R1(config-router)#do show run | section router eigrp 100
routereigrp 100
network 10.0.0.0
network 192.168.12.0
no auto-summary
R2(config)#routereigrp 100
R2(config-router)#noauto-summary
R2(config-router)#net192.168.12.0
R2(config-router)#net192.168.23.0
R2(config-router)#net172.16.0.0 0.0.0.255
R2(config-router)#net172.16.1.0 0.0.0.255
R2(config)#routereigrp 100
R2(config-router)#nonet 172.16.1.0 0.0.0.255
R2(config-router)#net172.16.1.0 255.255.255.0
R2(config-router)#do show run | section router eigrp 100
routereigrp 100
network 172.16.0.0 0.0.0.255
network 172.16.1.0 0.0.0.255
network 192.168.12.0
network 192.168.23.0
no auto-summary
R3(config)#routereigrp 100
R3(config-router)#eigrprouter-id 3.3.3.3
R3(config-router)#noauto-summary
R3(config-router)#net192.168.23.0
R3(config-router)#net192.168.0.0
R3(config-router)#net192.168.1.0
其它配置方法：（下面的三种配置方法，show run的结果是一样的）
R2(config)#routereigrp 100
R2(config-router)#noauto-summary
R2(config-router)#net0.0.0.0
R2(config)#routerei 100
R2(config-router)#noauto-summary
R2(config-router)#net0.0.0.0 255.255.255.255
R2(config)#routerei 100
R2(config-router)#noauto-summary
R2(config-router)#net0.0.0.0 0.0.0.0
此种配置方法的问题：
1：会把本地所有接口通告出去
2：如果本地存在出口配置的静态默认路由，也会被通告给邻居
R2(config)#iproute 0.0.0.0 0.0.0.0 s1/1（只能是出口配置的静态路由）
R1#show ip route eigrp
172.16.0.0/24 is subnetted, 2 subnets
D 172.16.0.0 via 192.168.12.2,00:03:17, FastEthernet0/0

6：查看EIGRP路由表
R2#show ip route eigrp
10.0.0.0/24 is subnetted, 2 subnets
D 10.1.1.0 via 192.168.12.1,00:05:05, FastEthernet0/0
