NSSA area default distribution

Hello,

I have the 2.9.30 routeros.
I have set up one routerboard as a nssa area member and one Cisco 871 as the ASBR between area 0 and the nssa area.
When i configure the cisco just to be part of the nssa area then routers establish full adjacency but when i configure the cisco to also originate default route into the nssa area then the neighborship stays on two way.


Has anybody experienced the same problem ?
