Mere deprecation does not stop propagation of such paths.
That's very true, but it *does* move us in the right direction -- saying "Aggregation that results in AS_SETs is prohibited, off with your head" isn't going to fly in the IDR WG when there are routes that use them... Suggesting the people do not perform aggregation that results in the creation of AS_SETs (and AS_CONFED_SETs), and that operators filter such announcements will lead to a time where they just don't exist any more [0] (and then can be removed from the protocol). We are also specifying that new BGP work does not need to support AS_.*SET ;-) W -- "Being the Fun-Police in the global Internet is a thankless - and probably futile - task." -- R.
