• OSPF综合实验


    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
