Allan, A. Bragg, P. Unbehagen Status: Standards Track Stream: IETF Date: April 2012 Mailbox: Donald.Fedyk@alcatel-lucent.com, Peter.AshwoodSmith@huawei.com, david.i.allan@ericsson.com, nbragg@ciena.com, unbehagen@avaya.com Pages: 37 Characters: 88465 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-isis-ieee-aq-05.txt URL: http://www.rfc-editor.org/rfc/rfc6329.txt 802.1aq Shortest Path Bridging (SPB) has been 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 Ethernet 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, which includes point-to-point, point-to-multipoint, and multipoint-to-multipoint variations. This memo documents the IS-IS changes required to support this IEEE protocol and provides some context and examples. [STANDARDS-TRACK] This document is a product of the IS-IS for IP Internets Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
