Sonos integration

 

Hello everyone,
?
I believe I may have come across a Sonos module within the group that communicates via IP address or device name.
?
I'm reaching out because I'm experiencing difficulties communicating with the Sonos device within its VLAN. My CP3 is unable to detect any devices, despite ensuring that all mDNS packets are properly routed between VLANs.
?
Now I am not able to find it in the file section and no information in messages.
 

How did you ensure the mDDNS packets were traversing across VLAN's? I
thought that can't happen.
 

In addition to an mDNS repeater, you may also need to implement an IGMP-proxy.?? That is particular the case if you have an iPad on an different subnet then the Sonos.? I would imagine the same is true for the CP3.

You may also need to implement IGMP snooping and Querier on your switches for both VLANs.
 

My question is why are you using VLANs for what I *assume* is a residential install...Is there a specific use-case?
And yes, I know that they have their place/uses but I think that much of the application of them stems from over-marketed network systems by a few of our channel's vendors years ago...
It is very rare that I have had specific needs for VLANs in our resi projects.?
 

Hi,
?
I have enabled the mDNS reflector, which allows multicast packets to route across different VLANs.
I can debug them in the router console using the tcpdump command.
