Even if i agree on some of your points we obviously have very different opinions. And it is kinda funny that you've linked a documents that says """ Maintain your peering policy The route server has built in filters that allow you to maintain your peering policies """ How could I maintain my peering policy if for whatever reasons the route server is adding its ASn in the PATH? Anyway, as said, i agree that the are some very particular cases in which that is needed. On top of all of them: the BGP stacks that rely on that behavior for whatever reason. That said i would like to clarify that i'd really prefer that the author use MUST instead of SHOULD (because, in my opinion, we should have those stacks fixed instead of adjusting a standard to embrace them) but i agree that it may not be advisable for the time being. So i think that we can use SHOULD and add further clarification that explains why that should be avoided when possible. Regards -- Marco
