Device - CRS326-4C+20G+2Q+ and CRS309-1G-8S+
Firmware - 7.16
Hello,
I have issues forwarding IGMP queries from my router between the LAN ports of the mentioned devices. IGMP queries are included in the VLAN tag.
IGMP Query → etherX → CRS326-4C+20G+2Q+ → etherY
IGMP Query → etherX → CRS309-1G-8S+ → etherY
Bridges on both are configured this way

Using “/tool/sniffer/quick interface=etherX” but do not see them on etherY
Tag stacking is enabled as I need to add tag between etherX and etherY on CRS326-4C+20G+2Q+
Tag stacking is not used on CRS309-1G-8S+
Any ideas, why IGMP packets are not forwarded as other traffic?
Just FYI, the same bridge scenario works on CRS317-1G-16S+. IGMP queries are forwarded between LAN ports in VLAN tag.
