NSSA Doubt

Dear Expert,

I have a topolgy

EIGRP NSSA AREA 1 AREA0
R1 ---- R2 ---------R3--------------------R5 ------- R6
  |
  |
  | AREA 0
  |
R4

R1 - LOOPBACK - 1.1.1.1
R2 - LOOPBACK - 2.2.2.2
R3 - LOOPBACK - 3.3.3.3
R4 - LOOPBACK - 4.4.4.4
R5 - LOOPBACK - 5.5.5.5
R6 - LOOPBACK - 6.6.6.6

I am redistributing the route 20.20.20.0/24 from EIGRP to OSPF on R2, the
R2 is advertising this routes as E2 via R4.
R5 is learning this routes as N2 but its not advertising to R6 as E2.

Other Areas are learning the 20.20.20.0/24 via R2 (Advertising Router)

R5 is the highest loopback, it suppose to advertise , But its not ,why ?

If I shut the link between R2 & R4, other areas are loosing the
reachability for the prefix 20.20.20.0/24, why ?

With Regards

P.Saravanan
