Lab2 OSPF多区域配置

爱卫生

本练习的目标是：

1）了解OSPF的最小配置

2）配置OSPF的骨干区域

3）在ABR路由器上配置OSPF多区域

4）使用show命令进行相关验证。

附件包含拓扑、步骤及指令、验证三部分。

本实验通过Juniper模拟器实现，所有接口名称均为em开头。如果是实际设备请将此接口名称进行替换。

部分内容摘要如下：

The minimum configuration for OSPF in multiple areas is not much different from RIP, with the exception that OSPF does not require an export policy. OSPF will enter the links and networks into the LSDB for the area in which the interfaces are assigned. OSPF will then advertise those LSDB entries to adjacent routers without exporting the routes. To create additional areas in the OSPF network, configure the second area on the router's interface (or interfaces) that connects to the second area. In this recipe, we configure the second area, Area 0.0.0.1, on our router. This router acts as the ABR between the backbone area and Area 0.0.0.1.
      

Part Two: Single OSPF Area Configuration
      In this part, we will setup the backbone area (area 0) in between R1 and R2. The loopback interface in each routers are advertise to area 0.
