A new Request for Comments is now available in online RFC libraries. RFC 7172 Title: Transparent Interconnection of Lots of Links (TRILL): Fine-Grained Labeling Author: D. Eastlake 3rd, M. Zhang, P. Agarwal, R. Perlman, D. Dutt Status: Standards Track Stream: IETF Date: May 2014 Mailbox: d3e3e3@gmail.com, zhangmingui@huawei.com, pagarwal@broadcom.com, Radia@alum.mit.edu, ddutt.ietf@hobbesdutt.com Pages: 27 Characters: 61855 Updates: RFC 6325 I-D Tag: draft-ietf-trill-fine-labeling-07.txt URL: http://www.rfc-editor.org/rfc/rfc7172.txt The IETF has standardized Transparent Interconnection of Lots of Links (TRILL), a protocol for least-cost transparent frame routing in multi-hop networks with arbitrary topologies and link technologies, using link-state routing and a hop count. The TRILL base protocol standard supports the labeling of TRILL Data packets with up to 4K IDs. However, there are applications that require a larger number of labels providing configurable isolation of data. This document updates RFC 6325 by specifying optional extensions to the TRILL base protocol to safely accomplish this. These extensions, called fine-grained labeling, are primarily intended for use in large data centers, that is, those with more than 4K users requiring configurable data isolation from each other. This document is a product of the Transparent Interconnection of Lots of Links Working Group of the IETF. This is now a Proposed Standard. 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.
