Hi all openwrt geeks! =)
I have a rather unusual situation, I have an Openwrt virtual machine 18.06.4, on a PC that has a 1 - 10 gigabit optical network card and a 1 - 1 gigabit LAN adapter that the non-managed switch is connected to. PC can not IGMP snooping, a managed switch can solve this problem. But I wanted to find out if it could really be done? Or you can do without the unmanaged switch and vlan ports on the openwrt itself?
The following connection scheme is assumed, where an unmanaged switch can be replaced with a managed switch, for example TP-LINK TL-SG105E with the support IGMP snooping V1/V2/V3
