I have the correct prefix length (/56 as the provider advises).
The command radvdump shows me RA's coming from the provider and I get three subnets together:
2a02:a204:YY:XX::/64 dev vlan2 metric 256
2a02:a204:YY:20XX::/64 dev vlan2 metric 256
2a02:a204:YY:40XX::/64 dev vlan2 metric 256
They are assigned to vlan2. Are these two last ones the additional subnets that have to be manually defined and configured on br0?
How can I check why my br0 gets no addresses? Is there a way to debug it, get some logs? Not sure where the problem is - with my router or with the provider side.
Any hints would be highly appreciated. Thank you in advance.

Welcome to the forums
issue nr one, your dd-wrt build is way way WAY old. without an upgrade to latest and followed by a reset to default and reconfiguration from scratch, Im sorry to inform you, that I personally wont be able to go further.
Your build is years old and many many fixes went into dd-wrt since then. So thus unsupported.
This build below isnt the newest build but it also is a safer build for now.

Hi, not sure if you read my message right - my build is just 15 months old - it is not "years"
But anyway I will try to follow your advice and upgrade.

That did the trick! Thank you so much, now it is working.
Well, I can't use IPv6 yet (for whatever reason my router doesn't have a default route for v6), but now I have a v6 subnet on br0. It is /57 and I am wondering if it may cause any issues...

you are welcome... there is no need to change anything in GUI setup when using PD (prefix delegation). If you leave it as is, it will work out of the box in 99% cases. BS allways try to solve problems globally (setups must work for majority of ISPs):
Especially do NOT chane prefix lenght! You cannot demand lenght from ISP. No matter if it is /64 in the GUI you will get /48, /56 or /64 and thats something your ISP decides... Once you got working enviroment you can play with it:)
The only problem I had was with RDNSS and only with 1 old android (9.0) cell phone... I solved it with putting the relevant global address (in custom radvd) of the machine (address is in upper right corner of ddwrt gui).

Again, upgrade... 15 months old or 15 years or 15 days are not supported dont have the latest code fixes, security patches or whatever else you want to add to that list.
