Hi,
   
  If I understand this properly, according to the description, R2 is redistributing EIGRP learned routes from R1 in to the OSPF domain, hence R2 is the ASBR. Since R2 is learning these routes through EIGRP (AD - 90) these routes should appear in R2's routing table as "D". The "no-summary" is configured on R4 (ABR) and block's "Type 5 LSA's" from area0 being flooded to area 20.
   
  I think the answer should be
   
  1-B, 2-B, 3-A, 4-C
   
  Like to hear your thoughts
   
  Regards

  LAST WEEK'S ANSWER:

Answer: e

Topic Domain: 4a

Issues:

How will the routes appear on each router in this topology?

Solutions:

The routes appear as the native EIGRP on R1. On R2 the specific routes
will not appear as the result of the no-summary configuration for the
area. On R3 the routes appear as E2 and on R4 they appear as N2 due to
the NSSA configuration.
