[nsp] MPLS: a couple of questions

[Pierfrancesco Caci]

Hello,
I would like to know if there are limitations for MPLS and OSPF: do
all routers that have to share a vpn need to be on the same OSPF area?


Is it possible to have MPLS over MPLS? In other words, can a customer
of mine that sees his routers connected with VPNs (without seeing my
backbone) in turn sell VPNs to _his_ customers ?



(cust_of_cust)--(my customer)--(my backbone)--(my customer)--(cust_of_cust)
(    pop A   )  (   pop A   )                 (   pop B   )  (   pop B    )

The general idea here is that "my customer" is a separate branch of
our company and we (the backbone) don't want them to mess either with
our OSPF area 0 or with our existing mpls configuration. 

Thanks

Pf
