各位CU们你们好：

请帮我分析一下，以下拓扑图为什么会出现环路的现象：

这上是我在c4506上的故障现象：如下3w4d: %STANDBY-3-DUPADDR: Duplicate address 192.168.60.1 on Vlan60, sourced by 0000.0c07.ac3c

没配好唄。这个图好熟悉哦

qdigrp

就是我的呀，呵呵，

不就是生成树协议没有配好吗？我就不相信，我搞不定他！

以前这图xd发过的，当时问的好像是hrsp的问题

支持lz搞定

qdigrp

也是我发的，

请问各位，学习spanning-tree要从哪里开始学起？
最近我在网上找了些资料，看的我有点晕！概念不清楚！

如果有什么好的资料或link,请共享，非常感谢！！！！！！！！

qdigrp

是不是要在c_4506和c_3750的port channel 上配spaning-tree 中的loop guard呢
来防止环路的产生

qdigrp

真心希望有人给我指点指点

告诉过你了解决环路要用正统的STP方法。

你老找歪门邪道，这就是后遗症。
