The IESG has approved the following document: - 'IS-IS Extensions Supporting IEEE 802.1aq Shortest Path Bridging' (draft-ietf-isis-ieee-aq-05.txt) as a Proposed Standard This document is the product of the IS-IS for IP Internets Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-isis-ieee-aq/ Technical Summary 802.1aq Shortest Path Bridging (SPB) is being standardized by the IEEE as the next step in the evolution of the various spanning tree and registration protocols. 802.1aq allows for true shortest path forwarding in a mesh network context utilizing multiple equal cost paths. This permits it to support much larger layer 2 topologies, with faster convergence, and vastly improved use of the mesh topology. Combined with this is single point provisioning for logical connectivity membership (E-LINE/E-LAN/E-TREE etc). The control protocol for 802.1aq is IS-IS augmented with a small number of TLVs while the encapsulating data paths are respectively 802.1ad (Provider Bridges) and 802.1ah (Provider Backbone Bridges). This memo documents those TLVs while providing some overview. Note that 802.1aq requires no state machine or other substantive changes to ISIS. It is an intention that 802.1aq be simply a new NLPID and set of TLVs. Working Group Summary There are known, multiple implementations and there has been public interoperability testing. An implementation report is forthcoming though not part of this draft. Document Quality There are known, multiple implementations and there has been public interoperability testing. An implementation report is forthcoming though not part of this draft. Personnel David Ward is the Document Shepherd for this document. Stewart Bryant is the Responsible Area Director. RFC Editor Note As discussed at IETF80 Please will you proceed with this document to generate the final text, including getting the document through auth48 and allocating an RFCnumber. However then please hold the document until the authors provide the definitive reference for [802.1aq]. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
