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
