Last week i had real testing mood, so I got an idea to try 3.0beta2 on my production OSPF network (small network 3 areas, 12+ routers).
In the end I was able to find one interesting thing
THERE ARE 3 DIFFERENT ROUTING PACKAGES:
1) routing 2.9 (no comments)
2) routing-test 2.9 = routing 3.0 (<censored>)
3) routing-test 3.0 with completely new OSPF (written from scratch by Mikrotik)
Believe it or not, but it's ALIVE,ALIVE! (mean: working!)
P.S. In 2.9 I had problems with distribution of the multipath routes!
