A revision of the topology change awareness draft. Change log has been added. Changes from -01 to -02 1. Add domain ID field to BPDU channel message. 2. Allow TLVs for BPDU and MAC Purge channel message. 3. Change BPDU channel message. Make BPDU field from fixed field to TLV 4. Add Authentication Information TLV 6. Assorted editorial changes. Comments appreciated.

Filename: draft-yizhou-trill-tc-awareness Revision: 02 Title: Aware Spanning Tree Topology Change on RBridges Creation date: 2013-05-02 Group: Individual Submission Number of pages: 15 URL: http://www.ietf.org/internet-drafts/draft-yizhou-trill-tc-awareness-02.txt Status: http://datatracker.ietf.org/doc/draft-yizhou-trill-tc-awareness Htmlized: http://tools.ietf.org/html/draft-yizhou-trill-tc-awareness-02 Diff: http://www.ietf.org/rfcdiff?url2=draft-yizhou-trill-tc-awareness-02 Abstract: When a local LAN running spanning tree protocol connecting to TRILL campus via more than one RBridge, there are several ways to perform loop avoidance. One of them illustrated by RFC6325 [RFC6325] A.3 was to make relevant ports on edge RBridges involving in spanning tree calculation. When edge RBridges are emulated as a single highest priority root, the local bridged LAN will be naturally partitioned after running spanning tree protocol. This approach achieves better link utilization and intra-VLAN load balancing in some scenarios. This document describes how the edge RBridges react to topology change occurring in bridged LAN in order to make the abovementioned spanning tree approach function correct. The IETF Secretariat
