nssa no-redistribute command

Hey team,

I was doing a practice lab today and the lab gave me this task:

- Do not allow any external or inter area OSPF routing information to enter
Area 26 from R1. Do not use any prefix-based filtering techniques.

- I then read ahead in the OSPF config section and saw that I was later
going to have to redistribute a Loopback into this area. So I knew the
answer (or thought I knew)

Ok "area 26 nssa no summary" - should be easy points right?

I got the section wrong because the solution was looking for "area 26 nssa
no-redistribute no-summary"

I have read about the no-redistribute option, but am a little confused
still. To me, I do not see the difference adding this "no-redistribute"
option makes.

I am going to lab this up in for the next 1/2 hour or so and wondered if
anyone had any input, suggestions, etc...

Have a good night team,
