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