This document explains how to interconnect IPv6 islands over a
Multiprotocol 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
Multiprotocol 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.  [STANDARDS TRACK]
