James,
I know this has been discussed several times, but I can't stop myself...

A single IPv6 route will consume 4 x the space of a v4 route, whilst we are in the transition phase between v4 and v6 and having to allocate memory to both protocols adding potentially the equivalent to 70k to the routing table 'just because its easier' doesn't strike me as the most sensible thing to do in the world.
My understanding is that routing table growth is largely fueled by traffic engineering rather than multihoming. So while routing table growth is a concern, PI policies are probably not a large factor.
True, but thats no excuse to pour fuel onto the fire.
Transition between 2 IPv6 suppliers (unlike IPv4) "shouldn't" require the same level of manual reconfiguration due IPv6's complexity crying out for some form of automation in its deployment in the first place. What I believe we should be looking at is education of the differences between v4 and v6 rather than changing policy.
My further understanding is that desire for PI is mostly for non-technical reasons. I don't think anything can make this motivation go away. Companies want it.
Okay but the point about the allocation of resources is that it should be done for technical rather than just pure business/political/paranoid reasons. Everyone is saying that IPv6 will 'last forever' but they said the same thing about oil too J -- James Blessing 07989 039 476
