BGP communities I use the most: - Influence the transit provider BGP local-preference: customer preferred, customer backup, peer, and transit LP values - Only advertise routes to the transit provider customers and not their peers - Don't advertise routes to transit providers' peer ASx. - AS-prepend X times to transit providers' peer ASx. I've had a couple of situations where a CDN provider is sending all their traffic via one transit provider. A BGP community to not advertise or as-prepend our routes to that CDN provider would have been handy. Most transit providers only allow you to not advertise or as-prepend to their peers and not other customers. On Tue, Jan 23, 2018, at 12:17 PM, James Breeden wrote:
I've seen the onestep list but the presentation is helpful. I guess my question was moreso to the people side of communities vs the technicalities of communities - what ones do people find themselves using most often and what do they wish was available from providers that really isn't otherwise out there?
