Auto Attach is about automatically attaching network devices to SPB capable networks so that the services that a SPB network provides are available on less complex and lighter weight devices on which SPB capability is not desired or needed. SPB requires full IS-IS and other software. >From the standard IETF draft - Auto Attach was created to provide a compact >method of attachment for light weight edge devices without requiring all of >these three items ( SPB, PBB, ISID ) be fully implemented- a full SPB >implementation ( Backbone Edge Bridge ) of SPB requires significant compute >logic.
So - support for PBB does not make support for AAC unnecessary. -----Original Message----- From: Ben Pfaff [mailto:b...@nicira.com] Sent: Tuesday, October 14, 2014 10:42 AM To: Flynn, Dennis R (Dennis) Cc: Ludovic Beliveau; dev@openvswitch.org Subject: Re: [ovs-dev] [PATCH 0/3] auto-attach: Add support for IETF Auto Attach standard Does support for PBB make support for AAC unnecessary? The cited Internet draft says that it is for devices that "typically do not support SPBM, MAC-in-MAC (802.1ah), nor I-SID usage".
