Explanation:
From the Layer 3 perspective, the P-network is invisible to the customer routers, which are linked
with
emulated point-to-point links. The routing protocols runs directly between customer routers that
establish
routing adjacencies and exchange routing information.
The service provider is not aware of customer routing and has no information about customer
routes. The
responsibility of the service provider is purely the point-to-point data transport between customer
sites.Cisco Press – Implementing Cisco MPLS Study guide p.4-21
