I have to say that this looks like a nice solution to me, and I've
definitely had many people point me to OSPF. One problem is that I've
never run OSPF before. Some googling brings of a few results on
implementation, but can someone recommend a good place to look or a book
to get to really get it all figured out?
Thanks,
Alex
