Hi Catherine, Because you are using point to point sub interfaces on the one routea and one the other just using the real interface, OSPF behaves differently and has different helo / dead timers etc, and this is why you are not getting all your routes. You need to make sure that all ospf interfaces in the same area are of the same "network type" using the interface command ip ospf network
