| I've been looking over the 'advisory' attribute, mostly in preparation | for the upcoming RIPE-181 to RPSL conversion (RPSL does not have this | attribute). Shane, The advisory attribute is no longer used. To my knowledge, it was exclusively used when the NSFnet stopped paying for ANS's backbone and the policy makers needed a way to transition from merit's PRDB to merit's RA IRR database. It stopped being used once AS690 (ANS) put together it's incredibly complex aut-num. | | The advisory attribute itself suffers from a severe lack of | documentation. [...] Ya. We got lot's of flames for that. | And finally, | what should the method be during RIPE-181 to RPSL conversion? For AS690, just drop it. AS690 no longer exists as a publicly accessible ASN. For the others, I would suspect that they are just gorp that you mentioned. . . -Tom
