Apple TV Airplay not working if the SSID is different subnet with the Airplay even the mDNS enabled

[Small_Potato]

Dear all,

Please help and comment on my post.

Below is the topology.

SSID A, Cisco WLC and Apply are in 192.168.1.0/24 subnet.

SSID B is Vlan 2 and in 192.168.2.0/24 subnet.

No any acl is on the Router or switch.

After an iPhone connect to SSID A,   Airplay works quite well.

IF the iPhone connect to SSID B, the iPhone can search the Airplay. But the connection out message appears.

Below are my WLC setting.

Below is SSID A and B setting.

I will appreciate your help with this situation.
