一、拓扑图

二、实验要求

1、R5为ISP,其上只能配置IP地址;R4作为企业边界路由器，~~出口公网地址需要通过PPP协议获取,并进行chap认证。~~
2、整个OSPF环境IP基于172.16.0.0/16划分;
3、所有设备均可访问R5的环回;
4、减少LSA的更新量,加快收敛,保障更新安全;
5、全网可达

三、具体配置

1、配IP地址

3、OSPF优化

一、路由汇总

通过在不同区域的边界路由器（ABR）上进行路由汇总，减少了不同区域之间传播的路由条目数量，提高了路由效率和网络的稳定性。这里 R3 和 R6 对 172.16.64.0/19 进行汇总，R7 对 172.16.96.0/19 进行汇总。

通过在不同的 ASBR上进行域外路由汇总，减少了 OSPF 域内传播的外部路由条目数量，提高了路由查找效率，也增强了网络的稳定性。R12 对 10.1.0.0/22 进行汇总，R9 对 172.16.128.0/19 进行汇总

二、特殊区域

区域 1（末梢区域配置）

区域 2（非纯末梢区域配置）

区域 3（非纯末梢区域配置）

4、缺省

[R4]ip route-static 0.0.0.0 0 45.0.0.2
