最近公司网络及其不稳定,配置都是在核心交换机上做的 ,路由器只做出口网关,路由器上做了几条回程的静态路由
现在有时公司会突然间断网,然后客户机ping不通路由器,核心交换机也ping不通路由器,在路由器上ping一下核心交换机可以ping通,ping通后网络恢复正常,后来交换机上做了arp绑定,但是把交换机连到路由器的网线拔掉在插上,要等一小会才能ping的通
由于近期网络很不稳定,排查过环路 IP冲突 有时候总感觉莫名其妙的慢 外线的话是一条固定IP 两条ADSL
路由器配置如下
交换机配置如下

最佳答案
您好,以下是排查要点,请参考:
1、检查物理链路是否有问题。
2、调整端口的MTU看下。
3、检查路由器的CPU、内存、端口利用率是否高。
4、检查路由器内是否有相应的日志反馈。
5、关闭流量异常检测看下。
6、可考虑升级路由器的软件版本到最新。
