华为OSPF实验记录 拓扑要求：1，根据图示配置正确的ip地址2，根据图示配置ospf协议及所属的区域，使全网互通3，AR1上有两个环回接口，为了减少路由表规模，需要配置区域汇总4，AR3上引入了两个环回接口地址（通过引入直连可实现）import direct5，AR3上对引入的路由汇总6,区域1希望降低路由计算、存储压力 ，同时考虑网络扩展，需要保留引入外部路由的功能。7，区域3外来人员较多，采用较安全的方式保证路由交互的安全性配置记录简述：1、配置ip地址：略过不写。2、宣告ospf各区，由于area3 不与骨干区area0 直接连接无法学习到其他区域的ospf路由，这里需要用到虚链路 vlink-peer，配置简述：area2 下 ar4 配置route-id 4.4.4.4 , ar5配置route-id 5.5.5.5;ospf下ar4 area2 配置vlink-peer 5.5.5.5  ,下ar5 area2 配置vlink-peer 4.4.4.4 使area3建立虚链路与骨干区直接相连。 3、area1下的abr（ar2）设置路由汇总 abr-summary 192.168.0.0 255.255.252.0 讲两个环回接口的路由汇总成一条。 4、ar3下的两个环回接口引入直连路由，ar3作为asbr（自治系统边界路由器）引入外部路由，ospf 下配置： import-route direct。 5、asbr-summary 172.16.0.0 255.255.252.0 路由汇总。 6、ar1 ，ar2  在区域1 下分别配置 nssa ，干掉 4 5 类lsa 保留外部路由。 7、区域3，ar5 和 ar6 分别ospf area3 配置authentication-mode md5 1 cipher  admin  所有route的配置：[V200R003C00] #
