Hi, We have had a fair amount of discussions lately on and off this list about the explosion of routes in the DFZ as a result of people wanting PI space and the likes. Others are ofcourse if there is no NAT66 how do you handle multihoming of a small site - but that is besides the point here. I have been wondering - since BGP is all about reachability as a goal and not so much optimal routing/best path/etc. is the easy solution for growth in the DFZ not overly simple? The way I see it you will end up with three sets of routes that you will need to carry on your routers: 1) Own customer routes - these can be any prefix length between /48 and /64 2) Other LIRs aggregates in same RIR region - these are /32 and bigger 3) Supernets for other RIR regions - these are /12 or larger So it seems like the explosion of the DFZ can be managed by supernetting certain routes. Having come up with this idea my next was - ok what am I missing here since it seems a simple and easy fix that would work without breaking much if anything. Can anyone enlighten me why we should not want to head in this direction?
