EIGRP专题实验1:EIGRP基本配置和常用show命令复习

实验配置:

1:配置接口地址

R1(config)#interfa0/0

R1(config-if)#ipadd 192.168.12.1 255.255.255.0

R1(config-if)#noshut

R1(config-if)#interlo 0

R1(config-if)#ipadd 10.1.0.1 255.255.255.0

R1(config-if)#interlo 1

R1(config-if)#ipadd 10.1.1.1 255.255.255.0

 

R2(config)#interfa0/0

R2(config-if)#ipadd 192.168.12.2 255.255.255.0

R2(config-if)#noshut

R2(config-if)#inters1/1

R3(config-if)#interlo 1

R3(config-if)#ipadd 192.168.1.1 255.255.255.0

 

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 [90/156160] via 192.168.12.2,00:03:17, FastEthernet0/0
