Hi Stefan,
ABR of NSSA doesnt generate a default route into the NSSA area
automatically.
You have 2 options to inject a default route into the NSSA area
1. area 25 nssa no-summary <-- will generate a Type 3 (IA)
2. area 25 nssa default-information-originate <-- will generate a Type 7
(N2)
Hope it helps.
