Carrier-of-Carriers VPN Example—Customer Provides VPN Service

In this example, the carrier customer must run some form of MPLS (Resource Reservation Protocol [RSVP] or LDP) on its network to provide VPN services to the end customer. In the example below, Router B and Router I act as PE routers, and a functioning MPLS path is required between these routers if they exchange VPN-IPv4 routes.
