[c-nsp] Low end MPLS question

[Krzysztof Adamski]

I have been asked to design a mini MPLS network running on ADSL links
with PPPoE, it should look like this:

switchA -- routerA --- PPPoE ------ LNS --- switchB
             ------------ MPLS ------

Let me explain, each port on switchA would be a separate network that
would connect to a corresponding port on switchB. There may be IP overlap
between networks.

My two questions are, is this possible, and what equipment would I use for
switchA and routerA?

I know I can do something similar with multiple routers, each having a
separate PPPoE connection and multihop on the LNS side, but I don't want
to have ~10 routers instead of routerA.
