Many thanks for the elaborate example.

Sure ;-)

This bothered my as well for the simple example (without label
stacking).  When thinking of smart LERs and dumb LSRs, IP-based FECs
should be needed at the borders only (e.g. R1 will have an entry towards
the IP adress of R4, the right border node, not towards R2).  I know
many MPLS networks use IP in the core to find best paths, i.e. using
OSPF-TE and the like, but can we as well build MPLS-only, non-IP cores
with mpls-linux?=20
