问题描述：
两台S7506做核心汇聚，开启协议有VRRP和rrpp
S7506-1上VLAN40-44接口地址为主用，备用在S7506-2
S7506-1VLAN50-54接口地址为备用，主用在S7506-2
问题1，备用S7506-2上VLAN40-44的虚拟VRRP状态一直在不停的在备用和主用之间切换，此时7506-1上主用状态没变化，出现业务不通，7506-1上RRPP状态也提示在变化（VLAN50-54一直稳定），找不出原因

最佳答案
看现象应该是S2交换机接说S1发送的VRRP心跳报文存在问题，有时候能收到，有时候不能收到。从而出现备主切换的情况，你可以抓包看看心跳包文的交互情况。

你好，我现在的处理办法是，将RRPP环从中间断开，目前看VRRP的主备状态正常
方便留个电话或QQ么？我把配置和出问题时的日志发给你看下
