Bridging VLANs over WiFi

Installing and Using OpenWrt Network and Wireless Configuration
1

I have a router and an access point connected over Ethernet with VLANs bridging. In addition, to my garage, I am extending one of the networks (VLANs) over WiFi. Is it possible to propate more then one network over WiFi?

router config /etc/config/network config device option name 'br-lan' option type 'bridge' list ports 'lan1' list ports 'lan2' list ports 'lan3' list ports 'lan4'

config interface 'lan'
option device 'br-lan.10'
option proto 'static'
option ipaddr '10.0.0.1'
option netmask '255.255.255.0'
option ip6assign '60'
option vid '10'

config interface 'guest'
option device 'br-lan.192'
option proto 'static'
option ipaddr '192.168.0.1'
option netmask '255.255.255.0'
option ip6assign '60'
option vid '192'

config bridge-vlan
option device 'br-lan'
option vlan '10'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4:u*'

config bridge-vlan
option device 'br-lan'
option vlan '192'
list ports 'lan1'
list ports 'lan4:t'

/etc/config/wireless
config wifi-iface 'default_radio0'
option device 'radio0'
option mode 'ap'
option ssid 'IoT'
option encryption 'psk2'
option key 'password'
option wnm_sleep_mode '1'
option wnm_sleep_mode_no_keys '1'
option multicast_to_unicast_all '1'
option network 'guest'
option bss_transition '1'
option ieee80211k '1'
option ieee80211v '1'
option time_advertisement '2'
option time_zone 'CET-1CEST,M3.5.0,M10.5.0/3'
option vlan '192'

config wifi-iface 'wifinet2'
option device 'radio0'
option mode 'ap'
option ssid 'guest-bridge'
option encryption 'psk2+ccmp'
option wds '1'
option key 'password'
option network 'guest'

config wifi-iface 'default_radio1'
option device 'radio1'
option mode 'ap'
option ssid 'main'
option key 'password'
option ieee80211r '1'
option mobility_domain 'd00f'
option encryption 'psk2'
option reassociation_deadline '20000'
option network 'lan'
option ieee80211k '1'
option ieee80211v '1'
option time_advertisement '2'
option time_zone 'CET-1CEST,M3.5.0,M10.5.0/3'
option wnm_sleep_mode '1'
option wnm_sleep_mode_no_keys '1'
option bss_transition '1'
option ft_over_ds '0'
option ft_psk_generate_local '1'
option vlan '10'

and respective config on the other ends of both Ethernet and WiFi bridges. Currently access point bridged wirelessely is non-DSA compatible but I am considering an upgrade there.

check gretap..
better over 11s mesh link where both wireless ends try to establish connection.
hotplug scripts needed to increase wifi mtu and transport full 1500B ethernet frames.

GRE tunnel I am considering as a last resort since it seems to me as ancient technology and probably not very well supported.
Was thinking also about the mesh. Good hint. Will explore it as a first.
How it is achieved with commercial APs? Wired only? Mesh? ...?

Please post output of

ubus call system board

from your OpenWrt device.
