[c-nsp] Network-to-network connection - MPLS / non-MPLS

[Mike]

What options are available for establishing network-to-network connections
between an MPLS network and a native IP network that has no current MPLS
capability?

The scenario I have is a single POP ISP (non-MPLS) that is desirous of
establishing a connection to a larger MPLS-based ISP.  The idea being the
ability sell circuits off the larger network's footprint and back-haul the
traffic to the smaller network, thereby extending the physical reach of the
smaller ISP.

I know this can be done using a IP aggregation type setup, but are there
other options available, particularly something that would provide
visibility at the lower layers for troubleshooting isolation purposes?


Thanks,

Mike
