Re: [Idr] WGLC on draft-ietf-idr-as-private-reservation-00

[Jon Mitchell <[e-mail]>]

As I've stated before, mis-configuration or improper use of private use
ASNs doesn't seem to be highly correlated to the size of the range.  If
this were an issue, I guess, we would expect that a network would be
leaking close to 1K ASNs today that then would expand to many thousands
or millions after the draft is approved?

Any network can filter private ASNs as well as various other types of
ASNs on ingress that they do not want to not accept/propogate.  This
draft will have no impact on whether people tend to do that correctly or
not in my opinion.  Folks who have no use for more than a thousand
internal use ASNs today are not likely to use this new range.
