It seems that this behaviour is built into the A-Expresses and probably has to do with the fact that it should be possible to find an A-express from the Airport setup utility program on the PC/MAC without the A-express having an IP adress first. After a reboot of an Airport Express I can see that the correct real IP address is snooped, but after a short time it falls over to the link local .x address, clients ( iPads for example ) see the Airport express just fine but cannot send audio to it since it tries to send to the link-local IP instead of the real one. AppleTV announces only it's real IP adress for the _raop._tcp service but the Airport express announces both its real ip adress and an ipv4 link local ( .x ) address.

We have three Apple TV's which works perfectly both picture/sound - problems seems to be the implementation of the Airport Express in combination with Bonjour GW in the WLC.Īfter som troubleshooting I can see that there is a difference how Apple TV and Airport Express announce their Bonjour services in regards to the airtunes service ( _raop._tcp ). Mdns snooping enabled for Airplay and Airtunes. WLC is running 7.4.115 and clients are sitting on a 2602 flexconnect ( Multimedia SSID is switched centrally ). We have issues with Airplay for Apple Airport express boxes.
