今天給大家分享的是OSPF綜合實驗，OSPF的理論一旦掌握好，實驗其實就非常簡單了，那麼下面大家就打開Ensp模拟器開啟實驗之旅吧！
實驗需求
按照圖示配置好IP位址，PC1網關指向為R8
OSPF劃分為4個區域，其中192.168.0.0/24，192.168.1.0/24，192.168.2.0/24屬于AREA 0，192.168.10.0/24屬于AREA1，192.168.4.0/24，100.0.0.0/24屬于AREA2，192.168.5.0，100.1.1.0/24屬于AREA3
為了防止鍊路中斷引起的骨幹區域隔離，在R3和R4上配置虛連接配接
在R5上配置到達172.16.0.0/24和172.16.1.0/24網段的靜态路由，并引入到OSPF内部
在R7和R8上配置預設路由，下一跳指向R5和R6
在ASBR上對172.16.0.0/24和172.16.1.0/24網段進行準确的路由聚合
在R3和R4上分别對AREA 0的網段進行路由聚合
将AREA3配置為NSSA區域
在R6上配置到達100.2.2.0/24網段的靜态路由，并引入到AREA3
在AREA0配置區域認證，密碼為123456
實驗步驟
01
配置相應接口IP位址及loopback 環回口位址
02按照圖示分區域配置OSPF
