我试图用 3 台 linux 机器创建一个 Web 集群（HTTP 和 FTP），其中数据包通过 NAT 平衡，我使用桥接接口和 HSRP，因为我使用 2 个路由器（使用 c3660 映像）来使所有高度可用。我正在使用 microxp 机器来测试连接。这是我的配置。

问题是当我只打开 1 个 linux 时它工作正常但是当我打开超过 1 个并尝试访问该网站时它不起作用并且 R5 路由器变得更慢并且在一段时间后显示 sysmalloc 错误，如下图所示

我认为这与 stp 配置有关，但我认为这一切都正确，但我认为这与网络循环有关。在 linux 机器上，我也配置了带 stp 的桥。这是我的路由器配置：
