Remote LAN / Multicast non working / Peer to peer optimization

[ygi]

Hello

I'm looking for advises and recommendation for our meeting room configuration. Here is the context:

• each meeting room have C9105AXW
• the visio system is a Polycom X50
• with a Polycom TC8 as control panel
• X50 and TC8 discover eachother with multicast address 224.0.0.200
• wireless clients and X50 need to be on the same subnet for efficient share screen with Zoom
• TC8 are on the same subnet too
• all deploy with central breakout in datacenter due to guest isolation needs

• wireless multicast is enabled in the WLC configuration

The issue we see is linked to the Remote LAN ports with the 9105AXW. The LAN ports are working fine, we get proper IP address and Internet access, and peer to peer ping works OK, but discovery via multicast does not works.

So I have one issue to solve and open to suggestion on one topic:

• what should I look for to troubleshooting my multicast issue where Remote LAN clients on the same AP does not discover eachothers?
• do you have any recommendations for the peer (wifi) to peer (remote lan) communication optimization?

Thanks
