this is a fascinating question to me. I wonder if the real reason different people prefer different approaches is more a personality thing than a real design thing. I prefer P2P subinterfaces, because at heart I think in terms of a wire that goes from here to there. I ususally do numbering schemes that have an internal logic to them and P2P is easier for me to deal with in terms of this logic. you are correct that split horizon can be turned off. You can make adjustments within any routing protocol execpt maybe for IS-IS either way. I guess in my case, I like things to be simple, and the more configuration I have to do, the more subtleties I have to worry about, the less I like it because it starts becoming work ;-> I'd be curious what some other folks who do a lot of network installation think. Over the past few years I've sold quite a few smaller networks, all hub and spoke, and mostly frame relay types ( although lately that has changed to more RLAN - ATM to DSL ) In every case I have done things the subinterface way because I personally believe it is easier to document and easier to troubleshoot.
