[SXR80] Need some clarification on VLANs and IGMP snooping
I know that the SXR80 doesn't support IGMP snooping with VLANs but I'm not sure what that means (I'm not a network engineer and reading the docs for both my smart switches and the Orbi, as well as se...
Hello Architekt,
The Orbi Pro doesn't natively support IGMP Snooping (as you found out) , but I think you can safely activate it on your other devices. IGMP Snooping is by default contained to one broadcast domain (VLAN) and would typically be set up per individual VLAN. The multicast traffic can be routed between VLANs as well, but it involves setting up L3 PIM (Protocol Independent Multicasting) and it becomes a lot more complex.
You mention having a Smart switch on the network as well. I am not sure if is a Netgear switch but I'll add a quick kb in case it is:

Thanks, that sheds some light on things, and that KB link is a much simpler explanation than the other internet related answers I found!
My switches are all Netgear all the way: these things are rock solid (I've had some for 10 years and they don't quit even in the least friendly conditions). The two main switches I use are the Netgear MS510TXM: I use one in my office and one in the garage which is that central switch that everything in the house connects to (and this central switch is what connects to the commercial firewall/router via the SFP+ 10Gbps port). Love the things, as I have my important devices using anywhere from 2.5-10Gbps NICs connected to them (one is in my office and connected to my computers) on the > 1Gbps ports.
The other two managed switches I use are also Netgear but not smart: they're the plus model, GS108Ev3. These are in my living room/media room for things like my gaming consoles and other ethernet devices that are <= 1Gbps. Regardless, everything connects to the one central MS510TXM central switch.
I'm not looking to route multicast traffic between subnets/VLANs, that should be confined to the subnet it's on, so I'm hoping that makes it easier. I'm looking to find the underlying cause of why there's sometimes tons of multicast traffic on the network, to the point where it has caused some issues with certain devices necessitating some switch resets to fix the problem temporarily.
I'll give that KB link a go, and see what happens when I enable it on the Orbi's port. Thanks for taking the time!
