Hi Andrew,   Thanks for all the valuable info you have provided, generally my setup is fitting into all what you have mentioned except for the RP, which i have changed as per your recommendation.   two points here, first my MS switches SW is MS 10.45 and is shown as up to date on the dashboard so if 11.x has been released, shouldn't it give me an update available status ?   secondly, I think the multicast is acting oddly on my network as there is connectivity disconnections happens when any changes made to multicast settings even on other VLANs/subnets which doesn't have the multicast routing enabled?, also when i go to core switch> Tools> Multicast routing and run this tool which i think should show me something like the multicast routing table it gives me nothing!!?? @m_Andrew  ...

Hello Gents,   I have a setup having 2 core switches (MS425-32) stacked operating at L3 and 2 server farm switches (MS350-48) stacked operating at L2. IPTV system components including Cisco DCM and receivers all physically connected to server farm switches which is then connected to the 2 core switches. all L3 interfaces are created on the core stack. we have 1 subnet/vlan for DCM input and receivers output interfaces, 1 subnet/vlan for DCM output, and 2 different subnets/vlans for set top boxes and TVs. my question is how the multicast should be configured on Meraki according to the best practice including: - Which interfaces should be configured with multicast enabled and which should be configured with querier? - Is it okay to have the interfaces created on the core while the multicast sources are all physically connected to the server farm stack? (core is all fiber interfaces and can't host the UTP connections). - How the randevous point interface should be configured? and should it be a separate interface or it's better to choose one for example the STBs subnet interface as the RP? - What's the best practices to have smooth multicast flowing through the network? - I have an issue that the channel stream becomes unavailable after a while (around 1 hour) then if we changed the channels the stream comes back normally then after a while goes again and so on, what could be the probable reason for that?   @m_Andrew @PhilipDAth  ...
