How does a VPRN service avoid the problem overlapping IP addresses from different customers?

You cannot have overlapping IP addresses. The service provider must ensure that its customers are all using discrete IP address space. Each VPRN service maintains a separate VPN routing and forwarding instance to separate customer routing information. A VPRN will ignore IP addressing information and use MAC addressing instead which are always unique. A VPRN will translate customer IP addresses to a private addressing scheme administered by the service provider.
