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
实验步骤
1. 配置相应接口IP地址及loopback 环回口地址
2. 按照图示分区域配置OSPF
