inherently wrong with using a single AS in multiple locations, and advertising discrete blocks of address space in each one. The best reason to do this is for a network that you eventually plan to merge - it eliminates issues of having to make major BGP configuration changes.Nothing inherently wrong with it if you're paying for transit, but good luck getting peering in multiple locations without presenting consistent views.
No problem at all. Use a tunnel. Going back to the original question: (A) Is there a reason have disconnected ASs? Sure. Does it make more sense than using multiple AS numbers? No. (B) Is there a reason to deaggregate? Absolutely. The biggest being rather bad internal allocations practiced by networks. Alex --
