Hi All, A new IS-IS draft has been submitted. Any comments are welcome. Best regards, Zhe -----邮件原件----- 发件人: internet-drafts@ietf.org [mailto:internet-drafts@ietf.org] 发送时间: 2017年3月13日 17:14 收件人: Chenzhe (Z) <chenzhe17@huawei.com>; Xuxiaohu <xuxiaohu@huawei.com> 主题: New Version Notification for draft-chen-isis-black-hole-avoid-00.txt A new version of I-D, draft-chen-isis-black-hole-avoid-00.txt has been successfully submitted by Zhe Chen and posted to the IETF repository. Name: draft-chen-isis-black-hole-avoid Revision: 00 Title: Avoiding Traffic Black-Holes for Route Aggregation in IS-IS Document date: 2017-03-13 Group: Individual Submission Pages: 9 URL: https://www.ietf.org/internet-drafts/draft-chen-isis-black-hole-avoid-00.txt Status: https://datatracker.ietf.org/doc/draft-chen-isis-black-hole-avoid/ Htmlized: https://tools.ietf.org/html/draft-chen-isis-black-hole-avoid-00 Abstract: When the Intermediate System to Intermediate System (IS-IS) routing protocol is adopted by a highly symmetric network such as the Leaf- Spine or Fat-Tree network, the Leaf nodes (e.g., Top of Rack switches in datacenters) are recommended to be prevented from receiving other nodes' explicit routes in order to achieve scalability. However, such a setup would cause traffic black-holes or suboptimal routing if link failure happens in the network. This document extends IS-IS to solve this problem. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
