OSPF Area Question

[alexpf]

Can you have an area be normal on 1 interface and NSSA on another interface?

Say you have area 1.

Area 1 has neighbor on interface 1 with normal type.

Can another Area 1 interface be brought online on different interface 2 with NSSA type?

I don't see why not as long as you have a 3rd interface in Area 0.  The different Area types represent different LSA types so you will see both LSA types in your LSDB.  An interesting question for sure as I've never actually done it.  We do run a lot of NSSA areas within our DC.
