CCIE Case Study:一个基础的EIGRP配置

这个练习的来源是 Routing TCP/IP Volume I, 2nd Edition 的 Page 29 7~ 299. 利用 Dynamips/Dynagen 的方式来进行基本的 EIGRP Configuration 练习。要进行这个 Lab, 必�要在自己的电脑上安�b Dynamips/Dynagen. 详细的安装方式请参考网上的资料!

Dynamips/Dynagen 的设定档如下：

配置:

# Another simple dynagen configuration file # autostart = false ghostios = true [localhost]     [[7200]]     image = \Program Files\Dynamips\images\c7200-jk9o3s-mz.124-12.bin     npe = npe-400     ram = 160         [[ROUTER Earhart]]     console = 2001     s1/0 = Lindbergh s1/0     s1/1 = Cochran s1/0     [[ROUTER Lindbergh]]     console = 2002         [[ROUTER Cochran]]     console = 2003

其中的 IOS 档案，请寻找正常管道取得。

三个 Routers 的 Initial configuration 如下：

配置:

hostname Earhart ! interface Loopback0  ip address 172.20.10.1 255.255.255.0 ! interface Serial1/0  description "Connect to Router Lindbergh S1/0"  ip address 172.20.15.1 255.255.255.252 ! interface Serial1/1  description "Connect to Router Cochran S1/0"  ip address 172.20.15.5 255.255.255.252 !

配置:

hostname Lindbergh ! interface Loopback0  ip address 192.168.16.1 255.255.255.0 ! interface Serial1/0  description "Connect to Router Earhart S1/0  ip address 172.20.15.2 255.255.255.252 !

配置:

hostname Cochran ! interface Loopback0  ip address 192.168.17.1 255.255.255.0 ! interface Serial1/0  description "Connect to Router Earhart S1/1"  ip address 172.20.15.6 255.255.255.0 !

需要输入的指令如下：

配置:

Earhart(config)# router eigrp 15 Earhart(config-router)# network 172.20.0.0 Earhart(config-router)# exit Earhart(config)#

配置:

Lindbergh(config)# router eigrp 15 Lindbergh(config-router)# network 172.20.0.0 Lindbergh(config-router)# network 192.168.16.0 Lindbergh(config-router)# exit Lindbergh(config)#

配置:

Cochran(config)# router eigrp 15 Cochran(config-router)# network 172.20.0.0 Cochran(config-router)# network 192.168.17.0 Cochran(config-router)# exit Cochran(config)#

当所有的设定做完之后，结果如下：

配置:

PS: 这个 Lab 基本上很简单。但是，对完全�]有设定过 Cisco 路由器的人来说，还是会有点困难的。所以，通过这样的方式，让没有机会碰到路由器的人，也可以在自己的家里练习。

另外，也希望大家可以说出自己的想法与意见。
