The fact that I choose to stick 701 in an AS_PATH attribute on a prefix I advertise in order to stop that prefix from propagating into 701 is entirely my own business, and it's a practice which, although apparently not commonplace, has been a well-known part of the IDTE toolbox for many years.
For whatever reason, technical, political, or pure whim, I don't want AS Y to receive any of my announcements.

Communities are optional transitive attributes. No one is required to act on well-known communities. Kris
