ER605 (version - 1.2.1) this firmware does not support mDNS repeater. However currently only ER7206 received the update, see this post:

  @Somnus Happy New Year, apologies for the late response, my set up stopped working and in a pinch I had to revert back to my old setup and I was out of town. I purchased ER7206 v1 and updated to latest firmware 1.2.3. Still mDNS is not working as expected. Unable to control devices in IoT VLAN from secure VLAN. In mDNS setting added a rule with device type as "Gateway" and selected secure and IoT for networks. This doesnt seems to do the trick, which aludes me to believe there is more with regards to the setting that I might be missing. I have not set up any ACLs or firewall rules across my step up to test mDNS, if they need to be set let me know. 

Another behaviour I noticed (not related to the topic discussed here) is, wifi 6 devices (iPad pro 3 Gen, 4 x Windows PCs) not connecting to 6 GHZ band ( AP - EAP650v1 Version 1.0.3). I have enabled band steering but it does not seem to do the trick. Radio settings are in auto mode. Devices always connect to AC and not AX. Is this a known issue?

Happy new year!

I don't have ER7206 but I saw some people are discussing the same thing:

Per Hank21 it will be solved in next firmware.

For the 2nd question, you may note EAP650 supports Wi-Fi 6 does not mean it also supports Wi-FI 6E.

6Ghz is only available on Wi-FI 6E Access Points like EAP690E.

Sad things is that I still cannot find anywhere to purchase this model..

  @hiveal Bad news, friend.  They're not interested in updating v1 anymore.  They've released firmware for the ER-605 v2 and v1 users are being left behind.  Don't ask about it though, they'll ban you for bringing it up.

To airplay Apple devices, LG TV, and SONOS speakers from your secure network in an Omada setup, you'll need to configure the mDNS repeater feature. Here are the steps you can follow:

1. Open the Omada SDN Controller and go to Settings > Services > mDNS.
2. Click on "+ Create New Rule" to create a new mDNS forwarding rule.
3. Specify the parameters such as rule name, status, device type, network/VLAN for mDNS request/reply packets, and the services to be forwarded.
4. Make sure to enable the rule for the IoT VLAN (VLAN 20) and the Secure VLAN (VLAN 1) to allow communication between them.
5. Save the configuration and apply the changes.

Note that mDNS rules for access points (APs) and gateways are mutually exclusive, so ensure that you have the correct settings for your devices.

If you still encounter issues, you may need to check if IGMP snooping is enabled on your network devices and if there are any permit policies blocking the communication. Additionally, make sure that all devices are connected to the WLAN and that their firmware is up-to-date.
