You do not need the OSPF "neighbor" command on the spokes. It is only
need on the hub. As a side note, you can not put the OSPF "neighbor"
command on the spokes if they also have the "ip ospf priority" command
applied to the interface.

Hi Micheal,
Looking thru ur configs,for a NON-BROADCAST OSPF
network type, who would also need a neigbour command
on the spoke..U could also remove the ip
split-horizon(though not needed cos ospf is a link
protocol- but it sure keeps ur config clean and easy
to troobleshoot..
Regards
Kunle
