	Title		: Connecting IPv6 Islands over IPv4 MPLS using IPv6 Provider Edge Routers (6PE)

This document explains how to interconnect IPv6 islands over a Multi-
   Protocol Label Switching (MPLS)-enabled IPv4 cloud.  This approach
   relies on IPv6 Provider Edge routers (6PE) which are Dual Stack in
   order to connect to IPv6 islands and to the MPLS core which is only
   required to run IPv4 MPLS.  The 6PE routers exchange the IPv6
   reachability information transparently over the core using the Multi-
   Protocol Border Gateway Protocol (MP-BGP) over IPv4.  In doing so,
   the BGP Next Hop field is used to convey the IPv4 address of the 6PE
   router so that dynamically established IPv4-signaled MPLS Label
   Switched Paths (LSPs) can be used without explicit tunnel
   configuration.

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.
