我有一个正在尝试桥接的 Cisco 860VAE-W。我之所以选择它，是因为我有兴趣了解一些有关 IOS 设备的知识——我刚开始学习这个非常原始的。

NAME: "C867VAE-W-A-K9", DESCR: "C867VAE-W-A-K9 chassis, Hw Serial#: GMK190700MQ, Hw Revision: 1.0"
PID: C867VAE-W-A-K9    , VID: V01 , SN: GMK190700MQ

我正在用一根摇摇晃晃的电线将它连接到澳大利亚 NBN（ Superloop FTTN），但 VDSL2 似乎连接正常。

在我看来，这Ethernet0是 DSL 调制解调器使用的虚拟接口，因此 和vlan1已添加到bridge-group 1. 该网桥上的任何内容都没有获得 IP 地址（有意义），然后bridge 1 protocol ieee似乎是正确的选择。我真的不明白GE0是如何进入桥接设置的，但我想它适用于其他人。最后， GE1配置了 IP 地址，因此仍然可以通过网络监控和管理设备。

所以从我最初的理解来看，这个配置看起来很合理，而且 DSL 方面似乎正在工作。但是，当然，我无法让坐在 Cisco 后面的 Orbi 成功获得 DHCP 租约。

我一直在筛选 Cisco 文档；它们很全面，但可能太全面了？感觉就像大海捞针。

那么，是的，如何将 Cisco 860VAE-W 从 VDSL 桥接到以太网？
