帧中继客户的需求 全互联 半互联 HUB and spoke 连接 解决方案 ISP 通过单独的客户建立多条PVC连接 全互联/半互联/hub and spoke方式 用户的接口 用户可以用不同的接口来满足自己向运营商的PVC. PVC 是虚链路 这点要记住哦 用户接口 点到点的物理接口
LMI 学习一个或多个DLCI,反向ARP协议可以为物理接口进行动态的映谢。通过物理接口可以形成点到点以及点到多点的TOP。但最好用静态映谢因为稳定些
点到点的子接口 LMI无法为逻辑接口动态解析DLCI 需要通过手工指定逻辑接口的DLCI号码，且点到点子接口只能制定一个DLCI。
点到多点的子接口 LMI无法为逻辑接口动态解析DLCI 需要通过手工制定逻辑接口的DLCI号码 点到多点子接口可以拥有多个DLCI和不同站点建立PVC
