What kind of workarounds? I am curious...

Okay, if you like you could also try [0] on bluetooth networks... I
never did it on bluetooth. Although I think it does not make any sense
because it makes only sense on a mesh network and so far I understand
this is the difference between bluetooth 4.x vs 5.x/upwards and
currently there is no mesh bluetooth 6lowpan support here (but mesh
bluetooth on link-layer is there). It's a star topology. I guess what
you could try out is ndisc-proxy setup which is mostly the same but no
routing involved and they share the same prefix.

I see, on this layer it would be linux-wpan and linux-bluetooth.
