Abstract:
This document explains how to interconnect IPv4 islands over a
Multiprotocol Label Switching (MPLS)-enabled IPv6 cloud. This
approach relies on IPv4 Provider Edge routers (4PE), which are Dual
Stack in order to connect to IPv4 islands and to the MPLS core, which
is only required to run IPv6 MPLS. The 4PE routers exchange the IPv4
reachability information transparently over the core using the
Multiprotocol Border Gateway Protocol (MP-BGP) over IPv6. In doing
so, the BGP Next Hop field is used to convey the IPv4 address of the
4PE router, a field is added in Network Layer Reachability
Information (NLRI) to convey the IPv6 address of the 4PE router, so
that dynamically established IPv6-signaled MPLS Label Switched Paths
(LSPs) can be used without explicit tunnel configuration.
