dell 6248交换机vlan间通信

vlan3998

交换机划分vlan2 IP 10.2.0.1/16     ；  划分vlan3 IP 10.2.0.1/16   现在网络是各个端口 都能ping通对应的网关 无论是10.2.0.0/16 还是10.1.0.0/16网段下面的PC都可以Ping通两个网关10.2.0.1和10.1.0.1 但是无法与这两个网段下的PC互通 求高手分析

yzkarchive

PC的网关是多少？

momingdekong

这还要高手分析。。。
明显是交换机没有开启ip routing

vlan3998

PC ping 10.1.0.1 10.2.0.1都可以通 就是PC所在网段网关与另一个网段的网关都可以PING通 但没办法PING通另一个网段的其他IP 就不通了

用ACL来做，

很多无奈，感觉不可思议。明明很简单的东西

配置没什么问题啊

掩码改成24位的看看
