r4 234路由器在不在一个网段 如在一网段你直接用一个物理接口就好了
现在我们做一个类似以太网环境 在同一个网段

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
