Can't see Apple mDNS services (Airplay, for e.g.) when service endpoint is
connected to a MAP

Question

I have two Unleashed R710 APs in a Mesh (running 200.2.9.13 build 186). Very simple setup - one WLAN, single VLAN.

There are a couple Apple Airport Express endpoints, that connect to the WLAN and offer AirPlay service.

The issue I'm seeing is that if the Airport Express connects to a MAP (as opposed to the RAP), I can't see or access its AirPlay service, even if my laptop connects to the same AP (MAP).

I'm not sure if Bonjour gateway would help (it's turned off now) since it is designed to bridge services across VLANs, but I only have one..

Any suggestions on what I should try?

Thank you!

i am not familure with the unleashed product setup. but i know that with our controllers, we couldn't see mDNS for google expeditions because we were tunneling the traffic back....just a thought.

New update: after 5 days, the problem has manifested again.

If I'm on a Mac connected to the MAP and run Airport Utility, it shows all Apple Access points as "can't find them", even if one of them is connected to the same MAP as my Mac.

Rebooted the MAP, forcing all wireless clients to move to the RAP - boom, everything is suddenly working. 😞

So the mystery persists - things work for a while, then stop. Actually this looks similar to the problem I had when I was running only a single R710 in a standalone mode (non-Uleashed). Had to reboot it once a week to restore the Apple services. 😞

It's possible the new update has mdns to unicast disabled because by default unleashed is configured to convert multi cast traffic to unicast.
