BGP communities usage for route origin, entry point
This started off as me being curious as to why a UUNet engineer I was talking to told me he could not understand why a network would support a feature such as BGP communities for identifying the origin of a route/network entry point. I tried to explain to him the advantage of being able to quickly identify where a route originates from (geographically), type of interconnect, type of "peer" (in this case I use peer for any BGP peer, customer or transit). I explained that it could be usefull for debugging and gaining more background info (route analysis is one of my favorite tasks) and some of the major and minor networks do provide such a feature/service. Still the engineer could not understand why and only saw this as a security issue, well I guess when you work for a network that does not provide any public looking glass or route server it's not really a surprise </rant> This triggered a thought, do many people actually use BGP communities to pinpoint a route origination point/type, and if so for what purpose (debugging, analysis, other) Thomas PS: If UUNet do actually support this feature please tell me who I should contact.
