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
