Hoped to see some changes in 2.9, but the problem is not solved
I have attached the drawing of my network setup to clarify the situation. There are two CSS326 switches and one CCR1009 router. The router is connected to the internet provider with IPTV. The switches are connected between with 10G optical cable and one of them is connected to the router (also with 10G cable). IGMP snooping on the router is enabled, but it doesn't affects on my problem. When IGMP snooping on both switches is disabled, everything works and IPTV clients can watch their TV channels. But if I enable IGMP snooping on any switch (or both of them), everything brokes and no one can watch TV. The most strange thing is that if I enable IGMP snooping on "Switch 1", IPTV stops working on "Client 3" and "Client 4" ! I don't see any adequate explanation of such behavior... And when I disable IGMP snooping on switches, it takes about 5 minutes to everything become working again, it's also very strange.
Can anyone explain what's happening here?
