into production. That bug is still not fixed. Since confederations are very widely used, and no one else found this bug, and yet we have hit it nearly immediately, there is some sort of logical problem here. If something as simple as AS_PATH prepending in confederations does not work, I have some big reservations about things that are much more complex than that.
Alex, there are some promising local isps that have large bgp networks with confederations and the confed behavior is fine. I am not sure what you mean by as path prepending in confederations, but if you are talking about the routers not taking into account the confederation member AS's in the overall as path length when doing route selection, than that is what was expected by most people using confeds.
No, I am talking about Junipers PR#13233. Your friendly Juniper Systems Engineer should be very glad to explain to you what exactly that means. Alex
