<b>EIGRP区域注入静态路由的三种方法</b>

拓扑图

<a href="http://blog.51cto.com/attachment/201202/160519185.png" target="_blank"></a>

R2为外网,R1为边界路由器。R3,R4为内部路由器

基本配置

R2配置:

R2#sh run

Building configuration...

Current configuration : 794 bytes

!

version 12.4

service timestamps debug datetime msec

service timestamps log datetime msec

no service password-encryption

hostname R2

boot-start-marker

boot-end-marker

enable password cisco

no aaa new-model

memory-size iomem 5

ip cef

no ip domain lookup

interface Loopback0

 ip address 2.2.2.2 255.255.255.0

interface Serial0/0

 ip address 12.1.1.2 255.255.255.0

 serial restart-delay 0

interface Serial0/1

 no ip address

 shutdown

interface Serial0/2

interface Serial0/3

ip http server

control-plane

line con 0

 exec-timeout 0 0

 logging synchronous

line aux 0

line vty 0 4

end

R1配置:

R1#sh ru

*Mar  1 00:21:11.123: %SYS-5-CONFIG_I: Configured from console by console

R1#sh run

Current configuration : 1011 bytes

hostname R1

 ip address 1.1.1.1 255.255.255.0

 ip address 12.1.1.1 255.255.255.0

 ip address 13.1.1.1 255.255.255.0

router eigrp 90

 redistribute static

 network 1.1.1.0 0.0.0.255

 network 13.1.1.0 0.0.0.255

 no auto-summary

ip route 0.0.0.0 0.0.0.0 Serial0/0

R3配置

R3#sh running-config

Current configuration : 922 bytes

hostname R3

 ip address 3.3.3.3 255.255.255.0

 ip address 35.1.1.3 255.255.255.0

 ip address 13.1.1.3 255.255.255.0

 network 3.3.3.0 0.0.0.255

 network 35.1.1.0 0.0.0.255

方法一:

重分布

边界路由上做静态路由,然后重分布到内部路由器和三层交换机

在EIGRP进程中redistribute static

R3上路由表

方法二:

network 0.0.0.0

R1上做默认路由,再宣告network0.0.0.0

与重分布静态路由明显区别在于管理距离,重分布为170,而此方法还是为EIGRP的90

R3的路由表

方法三:

ip default-network

边界路由器上:

全局配置模式下

ip default-network [外网主类地址]

这里是ip default-network 12.0.0.0

进入EIGRP进程配置

network  [外网主类地址]

这里是network  12.0.0.0

本地有外网主类路由

配置一条静态路由或者关闭EIGRP的自动汇总

在这里是配置 ip route 12.0.0.0 255.0.0.0 null 0

 此方法不需要默认路由

R1的路由表

注意点:带星号的就是默认路由
