Yup. I like using OSPF to set up the mesh to the loopbacks and then ibgp as the IGP.

yes... and align your setup with your physical topology(so making it useful); use other proto for mapping your infra, etc, etc,..

Link-state protocols are evil, and when they break, they *really* break. I still do not see a compeling argument for not using BGP as your IGP.
Slow convergence.
As well there is the issues of running a full iBGP mesh. I've actually been doing it, and now that I'm about o add my 5th router, OSPF is looking a lot better than configuring 4 more BGP sessions. I've heard some people recommend a route-reflector, but that would mean if
I personally prefer using IS-IS for loopback/infrastructure routes, and I use confederations for my IBGP. If a confederation ever gets to large, I can always add a route-reflector inside the confederation. Ralph, you have never failed to amaze me with your love for WCP (Worst Current Practices.) Derek them. the
route-reflector goes down you're screwed.
