I don't think this is the ask here. Today NO_EXPORT takes no parameters. I think it would be of benefit to all to be able to signal NO_EXPORT TO ASN_X in a common (std) way across all of my peers connected to ASN_X. Moreover policy on all vendors could understand it too without you worrying to match YOUR_STRING and translate into some local policy. That is by no means taking away anything you have at your fingertips .. it just adds an option to talk common policy language.
This already happens today, but mostly in a commercial relationship (customer and provider). While not technically impossible, I struggle to see operators opening up their networks to peers they hardly personally (or commercially) know with such a feature, custom or standardized. I suppose the bigger question is - can we trust each other, as peers, with such access to each other's networks? Mark.
