MPLS AToM 以太网接入方式
好久没写博客了，闲着无聊，写一篇： 某企业利用运营商MPLS骨干网组网，想要详细了解mpls atom及ospf等相关知识，各位自己查一下资料，这里就不累述了，这里仅给出了设备的配置。
1.场景：某企业总部及几个分支机构租用运营商的MPLS线路组网，全网跑OSPF协议，利用 MPLS 实现点到点的二层服务。配置包括运营商里的设备及总部、分支机构的配置，为了更加接近实际工作情况，分支机构有的采用子接口，有的采用物理接口接入MPLS骨干网。
2.网络拓扑：
上面的拓扑中分支机构2、分子机构3采用子接口方式接入，分子结构4采用主接口接入方式；总部肯定采用子接口接入方式（没啥好说的）。
3.设备配置
