Are MPLS or SR too heavy a bat?
MPLS was not an option at the time. It might become one.
MPLS with nested labels, which is claimed to scale because nesting represents route hierarchy, just does not scale because source hosts are required to provide nested labels, which means the source hosts have the current most routing table at destinations, which requires flat routing without hierarchy or on demand, that is, flow driven, look up of detailed routing tables of destinations at a distance.
