RE: OSPF NSSA to EIGRP redistribution

Any specific issues?

The only tip I can think of is that with an NSSA area in OSPF, you usually
do NOT want your ABR and ASBR to be the same router. Especially if you want
to aggregate/filter the external routes injected into OSPF from EIGRP at the
ABR (when they are translated from Type-7 NSSA LSA's to TYPE-5 External
LSA's). If you make one router a ABR/ASBR then the router will ("should";
Cisco has a warning that the router might get mixed up) treat the external
routes as if the ASBR functionality is in the backbone area and inject a
default into the NSSA (you may have to turn a knob to originate the default
route).
