Please just clarify the following point: do you intend to advertise paths containing AS numbers belonging to other entities on the public Internet without the permission of the owners of those AS numbers? You admit that youdon't know what the consequences of this injection will be.
Prepending announcements with remote AS numbers has been a well-known technique for preventing prefixes from propagating to particular ASes for a long time.
The AS_PATH attribute is a loop detection mechanism, and a determinant in path selection. What other magic is there in it that requires such careful consideration? Why should anybody need to get permission from remote operators before deciding what attributes to include in their own advertisements?
Do I need to get permission from Sprint before I include 1239:100 as a community-string attribute on my own advertisement, too?
It seems to me that there are enough issues with this type ofexperimentation *with* the permission of the AS numbers you plan to use. But the ethical issues with using them without such permission seems to me to beinsurmountable.
The ethical issues seem to be non-existent, to my way of thinking, and hence trivial to surmount :-)
