通过L3以太网的OSPF路由

Question

我一直在做下面的设置，基本上我不能让OSPF填充L3交换机的路由表。我已经正确地设置了他们之间的L3以太通道与适当的地址。我附上了一些截图供进一步分析。

OSPF公布的唯一路由是我没有设置的默认路由。我手动设置每个路由器的路由器ID，并简单地创建了一个OSPF进程，并将区域0分配给所有路由器。

IP路由也已在L3交换机上启用。

提前感谢

Answer 1

您没有正确配置OSPF。

您需要添加网络语句来定义参与OSPF的接口以及它们所处的区域。最简单的方法是将所有接口都包含在区域0中。将此命令添加到OSPF配置中：

 router ospf 10
 network 0.0.0.0 255.255.255.255 area 0

Answer 2

路由器协议只会为路由做广告：

• 通过此路由协议从其他路由器接收到
• 在配置此重新分配时，从其他路由表(包括连接的和静态的)重新分发，例如，如果配置中有redistribute connected
• 手动配置，通常使用network语句在OSPF中提供转发表中存在的路由。

另外，对于OSPF，您必须使用"network“语句来配置参与OSPF进程的接口。

例如：

• 您有两个具有IP地址192.168.0.1/24和192.168.1.1/24的接口
• 如果您将OSPF配置添加到network 192.168.0.0/24中，则进程将只使用第一个接口。
• 如果添加network 192.168.0.0/23，则两个接口都能够建立关系。
