Can someone please help determine why networks directly connected to R1 are
not being entered in the OSPF database and therefore not being advertised to
R2. I thought all directly connected networks (less loopbacks) are
automatically advertised via the OSPF process running on that router. Also,
notice that R1 Loop1 and R2 Loop0 are in the ospf database... why isn't R1
Loop0?
