The IESG has approved the following document: - 'Connecting IPv6 Islands over IPv4 MPLS using IPv6 Provider Edge Routers (6PE) ' <draft-ooms-v6ops-bgp-tunnel-07.txt> as a Proposed Standard This document is the product of the Inter-Domain Routing Working Group. The IESG contact persons are Bill Fenner and Ross Callon. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ooms-v6ops-bgp-tunnel-07.txt Technical Summary 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. Working Group Summary The v6ops working group had consensus to develop this approach, and handed the document off to the idr working group for its BGP expertise. There were no comments on the document during the idr WG Last Call. Protocol Quality There are multiple implementations of this specification. Specifically there are two implementations by the router vendors, and three implementations by the network test equipment vendors. The full implementation report is available (see http://www.ietf.org/IESG/Implementations/Implementation_draft-levy-idr-6pe-survey.txt). Note to RFC Editor Please publish this version, instead of the previously approved version 06. This version includes the changes described in the previous approval message's RFC Editor Note. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
