OSPF的练习
由要求2可知,所有配置基于172.16.0.0 16去进行划分,为了减少资源浪费,将图中看为六个区域,IP地址划分为172.16.0.0 19、172.16.32.0 19、172.16.64.0 19、172.16.96.0 19、172.16.128.0 19、172.16.160.0 19,将六个区域对应六个划分后的地址。为了进一步减少资源浪费:
对区域0的172.16.0.0 19进一步划分为172.16.0.0 30(P2P骨干链路...172.16.0.4 30、172.16.0.8 30)
对区域1的172.16.32.0 19划分为172.16.32.0 24(P2P骨干链路...172.16.32.0 30、172.16.32.4 30、172.16.32.8 30等等)和172.16.33.0 24(MA链路...172.16.33.0 29、172.16.33.8 29、172.16.33.16 29等等)和172.16.34.0 24(用户网段...172.16.35.0 24等等)
对区域2的172.16.64.0 19划分为172.16.64.0 24(P2P骨干链路...172.16.64.0 30、172.16.64.4 30、172.16.64.8 30等等)和172.16.65.0 24(MA链路...172.16.65.0 29、172.16.65.8 29、172.16.65.16 29等等)和172.16.66.0 24(用户网段...172.16.67.0 24等等)
对区域3的172.16.96.0 19划分为172.16.96.0 24(P2P骨干链路...172.16.96.0 30、172.16.96.4 30、172.16.96.8 30等等)和172.16.97.0 24(MA链路...172.16.97.0 29、172.16.97.8 29、172.16.97.16 29等等)和172.16.98.0 24(用户网段...172.16.99.0 24等等)
对区域4的172.16.128.0 19划分为172.16.128.0 24(P2P骨干链路...172.16.128.0 30、172.16.128.4 30、172.16.128.8 30等等)和172.16.129.0 24(MA链路...172.16.33.0 29、172.16.129.8 29、172.16.129.16 29等等)和172.16.130.0 24(用户网段...172.16.131.0 24等等)
对区域5(rip)的172.16.160.0 19划分为172.16.160.0 24(P2P骨干链路...172.16.160.0 30、172.16.160.4 30、172.16.160.8 30等等)和172.16.161.0 24(MA链路...172.16.33.0 29、172.16.161.8 29、172.16.161.16 29等等)和172.16.162.0 24(用户网段...172.16.163.0 24等等)
