You need to keep a few things in mind here: 1) Yes, you absolutely need split-horizon disabled on the hub 2) The neighbor command is completely up to you (or your lab). If you have the broadcast keyword on your frame-relay maps, you don't need it. If you do not, or are not allowed to have them you will need neighbor statements.
