Re: advisory attribute in IRR

The advisory field dates back to the old NSFnet. It was used there (and later by ANS) to determine the appropriate carrier to whom a packet would be given after the death of the PRDB and before routing policies were well established in the fullness of BGP4. I believe ANS stopped using this field some time ago and we stopped worrying about it. I believe the field is as dead as ASS690 will be in a week or two (or maybe already is). -- R.
