Devices:
MikroTik RouterBOARD wAP G-5HacT2HnD with OpenWRT r13630-635f111148
EnGenius EAP1300 with OpenWRT r14017-c90db26e05
I have a wifi setup with EAP and dynamic vlan assigment from a radius server.
Clients can connect and both unicast and broadcast (DHCP) works fine, but multicast does not, so IPv6 SLAAC does not work for example.
On the APs I can see the multicast packets being sent out on the the AP/VLAN interfaces (tcpdump -n -i wlan1.10 multicast), but none of the three clients (linux laptop and two iOS devices) receives them.
I have tried enabling multicast_to_unicast, multicast_snooping and hairpin_mode by hand in sysfs, doesn't make any difference, also tried disabling multicast_router.
It sometimes works on the MikroTik device, but mostly does not.
My wireless config (it's the same on both devices for both radios):
config wifi-iface 'myssid_5'
option mode 'ap'
option ssid 'myssid'
option hidden '1'
option encryption 'wpa3-mixed'
option auth_server 'authserver'
option auth_secret 'secret'
option dynamic_vlan '2'
option vlan_tagged_interface 'eth0'
option max_inactivity '1800'

Device is configured as an AP with multiple bridged VLANs.
The observed behaviour (via tcpdump) is that when SLAAC is used, the wireless client sends a Router Solicitation, it never gets from the bridge interface ( ath* -> br* -> eth0.* ) to the ethernet (VLAN) interface (and then never comes to the wired server).
The server eventually sends the (periodic) Router Advertisement, which actually gets through the other way ( eth0.* -> br* -> ath* ), and the client gets autoconfigured.
In the screenshots attached, ath* are the wifi virtual interfaces, eth0.* are the VLAN interfaces on eth0.
Behaviour is consistently observed over br-Wireless as well as br-WiFi_v6.
Please let me know if you need any other information.
This sounds very much like an issue in the Linux bridge layer which got fixed years ago. Feel free to open up a new ticket, or reopen if it's still reproducible with a recent version of OpenWrt.
