Yes it does all routers are aware of all existing networks etc.

It seems that “mishaM” advice from that post http://forum.mikrotik.com/t/2x-parallel-vpls-tunnel-in-the-same-time/36306/1 solved the problem.
At least on 2 test test routers, after removing transport addressthey get local and remote bindings assigned and VPLS tunel works.
Later I’ll check if it works in bigger network.
I have another question although i suppose it should be asked in newbie area 
“How do I make the router to label switch packets instead of routing them?”
