Local mDNS for Chromecast not working on WiFi

Hi All,

I have my fabric edge switches configured as local mDNS gateway. Chromecasts are connected through AP which are connected to floor edge switches. When I am connected with cable I can scan chromecasts but when I am on same AP with chromecasts I can`t scan. Global Multicast is enabled on WLC with AP multicast and mDNS snooping is disabled. I made packet capture on my machine and switch and I see that when I am on WiFi, my computer sending mDNS queries and switch is receiving packets. Then switch from it Anycast IP is sending packet to 224.0.0.251 with answer PTRs but these packets are not coming to my computer.

 

What can be the reason?
