Hi Ken,
Not sure if this helps but check your config against the book. You have "
Area 10 stub no-summary " while the
book has " Area 10 nssa default-information-originate"
Different animal. Though I do not believe this will correct your problem.
Try traceroute to 155.195.1.1 and see if
it dies on the other end of E0. I think in the diagram on Pg
810 the Internet router would have to be providing some
kind of default to dental_ho router. What's your opinion.
And lets not forget "whos' bedda than you"
Danny
