Greetings NANOG, Was hoping to gain some insight into common practice with using BGP Communities downstream. For instance: We peer with AS100 (example) AS100 peers with TW Telecom (AS4323). Since I happen to know that AS100 doesn't sanitize the communities I send with my routes. I can take advantage of TW Telecom's BGP communities for traffic engineering. Such as 4323:666 (Keep in TWTC Backbone). Would this be something that is generally frowned upon? Still under the assumption that the communities aren't scrubbed off my routes. Could I do this with other AS's beyond TW Telecom? Such as TW's peering with Global Crossing (AS3549)? Nick Olsen Network Operations (855) FLSPEED x106
