请教-华为交换机-冗余网络中VRRP不断切换
近日在原有网络扩容时,导致原来运行正常的VRRP出现不停切换,同时出现丢包和延时增大。请熟悉的朋友多多指教。
网络结构采用VRRP做冗余,两台三层交换机(huaweiS3328)做为网关,vlanif配置VRRP,下联两台级联的二层交换机(huawei s2016),以trunk相连。原来拓扑图如下:
扩容的动作就是按照原来的结构模型添加两台二层交换机(huawei s2403),添加完后,发现主备三层交换机huawei s3328出现告警。请看扩容后的网络拓扑及告警日志:

交换机的配置文件,没有提供,很难定位。
建议先检查STP协议是否配置正确。

估计是新加入的交换机的stp配置有问题。
700,800,900vlan之间有环路
顶一下。。。
最好把所有的配置都贴出来 可能是下层数据返回时形成环路 要不开Debug看下
我们分析也应该是成环了,检查之后发现STP没启用,准备调整一下STP,同时也要考虑上联vlanif4000的冗余。
这个问题太专业了,我现在业余玩玩华为交换机,真的不太清楚哈!
学,再学。把上网的时间去学习。
