【每日必学】利用CISCO AP 实现无线网桥的解决方案

发布作者：微思网络   发布时间：2017-06-20   浏览量：0次

实验需求：需要两个无线设备以太网口所接的主机，能通过无线设备互相通信。 

 图解：

如图，由于 A 栋与 B 栋之间的道路无法施工，为了使得 B 栋的主机能够与 A 栋的主机能够正常通信。在 A 栋与 B 栋楼顶安装无线 AP，通过 AP 中继做桥接，使得 B 栋的主机能够与 A 栋正常通信。

厦门计算机培训机构要求:通过配置使得 AP-2 成为无线中继，让 B 栋的 PC 通过 AP-1 获取 IP 地址能够与 A 栋PC 正常通信。

注：如图PC 可以通过有线连接到AP-2，也可以通过无线连接到AP-2。通过AP-2 从AP-1 那里获取IP 地址。
