两台S6720做了VRRP，并且作为客户端的网关，客户端出现多重网络

两台S6720做了VRRP主备，作为底下客户端的网关设备，在两台S6720上都配置了dhcp用来分配地址，客户端采用自动获取地址，在网络和共享中心那边看到有多重网络的字样，并且存在多重网络字样的主机都上不了网，可以ping通网关，但是ping不通公网。

如图：

主S6720的部分关键配置如下：

无

1：让客户尝试ping网关，发现可以通，但是ping不通出口路由器，在S6720上可以直接ping通出口设备。
2：检查PC的配置，网关必须为VRRP组的虚地址。
3：设备上的arp trace显示arp在两个设备之间漂，所以让客户在主备S6720分配地址的范围调整了一下，各占一半，发现故障现象依旧存在。

微软技术支持网站介绍是Adobe软件的Bonjour服务导致该问题。

在任务管理器禁用Bonjour服务，并删除C:\Program Files\Bonjour\mDNSResponder.exe，问题解决。

在客户端的网络和共享中心有碰到多重网络的字样时，可以在任务管理器禁用Bonjour服务，并删除C:\Program Files\Bonjour\mDNSResponder.exe。
