实验拓扑

实验需求

1、按照图示配置好IP地址，PC1网关指向为R8 2、OSPF划分为4个区域，其中192.168.0.0/24，192.168.1.0/24，192.168.2.0/24属于AREA 0，192.168.10.0/24属于AREA1，192.168.4.0/24，100.0.0.0/24属于AREA2，192.168.5.0，100.1.1.0/24属于AREA3 3、为了防止链路中断引起的骨干区域隔离，在R3和R4上配置虚连接 4、在R5上配置到达172.16.0.0/24和172.16.1.0/24网段的静态路由，并引入到OSPF内部 5、在R7和R8上配置默认路由，下一跳指向R5和R6 6、在ASBR上对172.16.0.0/24和172.16.1.0/24网段进行准确的路由聚合 7、在R3和R4上分别对AREA 0的网段进行路由聚合 8、将AREA3配置为NSSA区域 9、在R6上配置到达100.2.2.0/24网段的静态路由，并引入到AREA3 10、在AREA0配置区域认证，密码为123456
