[shim6] IPv6 multihoming

[Vlad Ion <[e-mail]>]

Hi,

For a year now whenever it comes to IPv6 telco implementations I keep facing
2 problems so I was hoping you can guide me towards find a group that deals
with these issues or discussion solutions. The 2 problems are related to
IPv6 multi-homing and access to the internet in IPv6 format for a quick
transitions from v4 to v6. Also I need some guidance as to what needs to be
done for a draft document proposal to be created about the proposed
solutions mentioned bellow and who needs to be involved in this process.

As far as multi-homing goes in IPv6 the solution discussion generated by
using provider-independent address space like mentioned in
draft-hain-ipv6-pi-addr-10 seems too complicated to implement efficiently
and generates a lot of unnecessary work. Because IPv6 will never really be
adopted by ISPs, telco and enterprises until it offers a feasible
multi-homing solution my proposal is that some solutions are redefined such
as provider independent address space and the 6to4 standard.

I propose that the 6to4 ip conversion space from ipv4 addresses to
2002::ipv6 space will be redefined as provider independent address space.
This way whoever wants to implement ipv6 with multi-homing can simply
redefine their existing IPv4 addresses in IPv6 6to4 format and have
multi-homing in ipv6. Everyone already uses ipv4 multi-homing with success
so I see no point in defining a new addressing system for v6 when everyone
can simply use the same v4 address space for multi-homing but converted in
6to4 format.

Also, another issue faced by whoever uses IPv6 is that access to the
internet in v6 format is limited so a proposal has to be made to the RIRs to
offer incentives such as free IPv6 space for anyone who implements 6to4
relay routers and advertises their existing v4 space in v6 format along with
the newly received free v6 space.

I believe that as long as ietf gets involved and a rfc is written on these 2
proposals starting with the redefining of  the provider independent address
space and its inclusion in the 6to4 format things will be a lot more compact
and give some additional momentum to the IPv6 migration process.

Best regards and I hope to hear from you soon,
