[c-nsp] Running MPLS across non-MPLS networks

[Greg Schwimer]

I have a situation where I need to run MPLS across a non-MPLS network (the
Internet) to connect two of my networks together.  We have looked at GRE,
but ran into issues and were later told by Cisco that running MPLS over GRE
is unsupported.

Any ideas as to a solution to this problem, aside from purchasing a
third-party service (circuit, etc)?
