Your thoughts on the matter are correct. Understanding the operation of
IBGP verse EBGP is the key. IBGP does not have a hop limit as EBGP does.
IBGP is for internal neighbors that have multiple paths to each other. So
if one path goes down, the neighbor can still be found with its loopback.
EBGP is for external peering with a hop limit of one. By useing a loopback
on an EBGP peer, that creates a hop count of two (one to the physical
interface and one to the loopback). I would do as you said, and consider
all IBGP to be loopback peers and all EBGP to be physical interface peers
unless directly stated not to or previous tasks do not all it.
