Assuming you want the two instances to be able talk to each other you just have to relax loop detection so that you will accept prefixes from your AS...
We basically treat each of our datacenter's as their own entity, using
separate space for each, but all with the same AS #. What Joel
mentioned is going to be the major catch, in that for each of the two
disconnected AS's to accept the opposite sites routes, you'd need to
relax BGP's loop prevention check (which looks for it's own AS #
within the AS Path of incoming routes).
I am not using cisco. From my understanding from your mail, I should
configure bgp as the following. Right?
What do I should pay attention also?
