路由器的配置就算是完成了。
在前面几篇文章中我介绍了PacketTracert中服务器的设置，再此不再赘述，在该实验中DNS服务器IP为：192.168.20.251；WEB服务器的IP地址为：192.168.20.253（[url]www.51cto.com[/url]）。 下面看看路由表吧： R1:

通过对路由表的观察我们知道网络已经联通了～
最后我们就在这个模拟器中小小应用一把吧：用PC0访问[url]www.51cto.com[/url]（192.168.1.253）。
实验：OSPF高级配置（三）绝对末节区域
2009-06-26 02:08:38
本篇只介绍绝对末节区域的配置，及实验结果显示。如需查看之前配置，可参看本专题前两篇文章（一）、（二）。 拓扑图：
将区域1配置为绝对末节区域，要R2、R3、R4均设置为末节路由器，并且R2不能转发汇总信息到区域1内（只通告给R3、R4默认路由）。 路由器配置： R2: R2(config)#router ospf 1
R2(config-router)#area 1 stub no-summary R3: R3(config)#router ospf 1 R3(config-router)#area 1 stub R4: R4(config)#router ospf 1 R4(config-router)#area 1 stub 查看末节区域内的路由表： R3#sh ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
