Thank you all who tried to help me with this problem. According CCO LSA
type-7 will not translate to LSA type-5 only if NSSA ASBR is NSSA ABR
otherwise it should. In my case NSSA ABR is not NSSA ASBR.
After playing with all possible combinations I gave up and recreated same
exact scenario on 3 other routers. It worked just fine. The problem was
in IOS 11.3(11a) on R2 I suppose.
