BGP Neighbor please help

I have a configuration on BGP that requires for 5 Neighbors 4 locally (same switch) and on that is at the end of a serial link, my question is does the neighbor need to directly connected or can I route the BGP information across the serial link and is thier any special config I need to put in either the serial routers or my BGP routers to make this possible.

Many thanks

Re: BGP Neighbor please help

iBGP does not require the peers to be directly connected interface.

eBGP are usually on directly connected interface. If you want to establish a eBGP seesion on a non directly connected interface, you need to use the "nei x.x.x.x ebgp-multihop" command. You might also need to specify the source address for the BGP session with the "nei x.x.x.x update-source " command.

Let me know if this answer your question.
