I was hoping that someone has come across the same issues we are experiencing with the Apple TV and WLC.
We currently have a Apple TV and iPhone same subnet connecting via Lightweight AP (different subnet) which connects to a Cisco3750 running IP Base. This connects to WAN routers managed by third party over a WAN and connects to far end Managed routers, these connect to other Cisco3750 IP Base and onto a 2504 Wireless LAN controller. We have used the the following document for WLC configuration;
We turn on Multicast globaly, with IGMP snooping enabled also enable Multicast Multicast under controller (only option available on 2504) and give the device MCast address 184.108.40.206 . The P2P blocking action is disabled. Going to Monitor Multicast we can see the Report for 220.127.116.11
and MGID. However the issue is at the Sender Receiver side the iPhone cannot see the Airplay on the iPhone that should be seen if the end to end stream is working.
My focus is now on the Cisco3750's, allthough I do not totally understand why the device needs Multicast enabled as the Multicast Join and Group Traffic is encapsulated in the CAPWAP Tunnel is it not?
Anyway I have enabled the only option "ip multicast routing distributed" and under the Vlans that connect to WLC and AP's the only option available is the "ip pim passive" there is no "ip pim sparese-dense mode"
Any help and assitance on this would be greatly appreciated. I am sure the WLC is configured correctly, but I suspect that this will not work due to the IP Base image on the 3750's not being able to run full multicast or we need to use unicast for this solution that the 2504 does not support.
