- After filtering out duplicates, local effects and anomalies caused by a few specific events, we find that there is an increasing trend in "baseline" churn over the past six years, but that this growth is quite modest, and much slower than the growth in the DFZ RIB size. I did comment on the RIB size, explained my point, by some chessboard example how bad the basic concept (DV) is. I learnt what LISP is doing to improve the situation: LISP is eliminating an additional factor I haven't even considered in the first place when I came up with these horribly high numbers of routes. So my question is, why is this group so much convinced of collecting routes rather than of collecting topological links ??? This is the #1 question and much more important than the CES versus CEE issue. Particularly when there are so many and so major technological additional advantages in case BGP provided topological information. And the hereby needed "update churn" is such minor, that it could be afforded as even some additional solution in parallel. I have been watching this discussion for about six or seven years, at least since the Prague meeting. I have expressed several times that it may take patience and I do know that all other DV-based solutions will be prioritized first. But how many more years does this group want to go on in this way? It seems to be easier to show that p equals np than to convince this group about the most obvious routing facts. Really, this #1 question deserves a severe discussion. Heiner
