Okay, I'm looking to be able to do something like customer ASN 65500 passes me a community to not advertise his routes to 174. If I have 174 as a transit or peer, great, don't advertise there. I would also push that out to all other transit or peer connections.
Okay, so they send me a community of 174:6000, meaning they want No-Export of 174. Would this be valid? Keep in mind this is purely an educated guess.
