Title : Address Allocation for PE-CE links within an
Author(s) : J. Guichard et al.
Filename : draft-guichard-pe-ce-addr-00.txt
Date : 24-Jun-02
This document proposes to allocate a block of globally unique IPv4
addresses for exclusive use by Service Providers that provide
[L3VPN] based Services. The Service Provider may use these addresses
for the provisioning of IP addresses to the links that connect
customer edge (CE) routers with provider edge (PE) routers (PE-CE
The main motivation for this proposal is to simplify the Service
Providers' operations by eliminating the need for the Service
Providers to acquire globally unique addresses for the links that
connect Customer Edge (CE) routers with Provider Edge (PE) routers.
An additional benefit of this proposal is that it conserves IPv4
address space by allowing multiple Service Providers to share the
same block of IPv4 addresses for provisioning of customer links.
This addressing scheme is not intended for use by VPNs that span
more than a single Service Provider, unless co-operation of addressing
structure is maintained to ensure uniqueness between providers.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
