Ok I understand the NSSA principal....... I am stuck on how to set up the
ACL for the OSPF distribute list in serial 0 part.

Router ospf 1
distribute list 50 in Serial 0

Access-list 50 deny 0.0.0.0 0.0.0.0

That doesnt work, because it blocks all traffic. How do I block just the
default route?

Heaven Help me attempt # 3 coming up Jan 15th............................

Thank You,

David
