As part of IETF review, the Routing ADs are looking over draft-ietf-pppext-trill-protocol-06. Not too surprising to me -- given that I still think it's far out of scope -- the text concerning IS-IS System IDs is causing trouble in that review. See this thread: http://www.ietf.org/mail-archive/web/rtg-dir/current/threads.html#01533 I wish I could leave the worms safely in the can, but it's looking like that might not be one of the options. Instead of the reference to Bill Simpson's draft, Stewart Bryant suggested replacement text like this: ISO/IEC 10589 states that it is the responsibility of the routeing domain administrative authority to enforce the uniqueness of the system ID. In cases where a zero configuration system is supplied the system manufacturer MUST install a suitable unique identifier at manufacturing time. One way to achieve this is for the manufacturer to use a unique IEEE MAC address following the allocation procedures normally used in the manufacture of an Ethernet interface. This tosses the issue back into the implementor's lap (which, incidentally, is exactly where I think the problem belongs), and suggests an existing and known solution where a MAC identifier may be allocated for the system itself and used as a global ID to construct the necessary IS-IS System ID. For use in this draft, I would alter the wording slightly to indicate that zero-configuration is strongly preferred for TRILL (as guidance), and that obtaining a suitable identifier is the implementor's responsibility, rather than just saying "in cases where." Would this change fly without breaking consensus? Or do we have to start over? -- James Carlson 42.703N 71.076W <carlsonj@workingcode.com>
