Hello Jun I think this is a misinterpretation of the mandate. Pointing on IETF work done outside SAVI like RFC-to-be 8505 and AP-ND does not constitute creating a solution yourself. It is in the interest of the reader to find the reference in your doc. Suresh, what do you think ? Pascal Le

Dear Pascal, Thanks for the explanation. You didn't mention your RFC-to-be 8505 in the previous email, so I didn't get what you meant. If you just hope we point it as a reference, I think that would be no problem. Best Regards, Jun Bi From: Pascal Thubert (pthubert) Date: 2018-11-13
