It is called carrier's carrier and is described in RFC2547bis section 9,
http://tools.ietf.org/wg/l3vpn/draft-ietf-l3vpn-rfc2547bis/draft-ietf-l3
vpn-rfc2547bis-03.txt
The basic idea is that the carrier MPLS network in the middle provides a
VPN for the client MPLS network, and LDP runs between the two networks;
the carrier providing this service ends up with a three rather than two
label stack. Cisco has an implementation if you need it.

Subject: MPLS over MPLS
Does anyone know if there is a way to run MPLS over MPLS? Currently we
have about 700 circuits on an MPLS network. I would like to be able to
run MPLS over the top of this network so that I can provide a layer 3
VPN for our customers a crossed the sites.
Any thoughts?
