Hi all,
Thank you for your replies, I am sorry I could not attend to it earlier
cause I was out of the country.
As many have said, distribute lists do not work if it is in the same OSPF
AS. This I found out the hard way, by trying distribute lists incoming and
outgoing on both routers. The route still appears in my OSPF area 0.
I would like to assume the following, however, I need confirmation:
Distrubute lists do not work within OSPF, due to the link state issue !
If you believe differently, and you can prove it please send me your config.
Mine is as follows : (on R2 as per the diagram at the botom !
Thank you for your assistance !!!
Ken

Perhaps some misconfigured command or IOS bug.
