This note adds definitions and clarification to "A Comparison of Scaling Techniques for BGP" 1, corrects some minor errors and clarifies points which may not have been clear in the original paper. It also adds a new analysis of the scaling properties of route-reflectors and confederations, leading to a new conclusion that route-reflection and confederations scale equally well in the general case and that the choice of the scaling technique employed by a network needs to be made on a basis other than the scalability metric we have analyzed.
