There are currently two forums where IPv6 multihoming solutions are
being discussed.

One is the IETF Site Multihoming in IPv6 working group:


The IETF working group has been around for a few years, but frankly
hasn't gone forward much.  Which is the reason that a few couple of
interested parties created is the IPv6 Multi-homers list:


Based on my understanding of the problem, our current notion of
multihoming is too limited - there will probably be a
"one-size-fits-all" solution to redundant connectivity in IPv6.
Solutions that have good properties for small sites don't support
necessary features for large sites.  This isn't bad - it just means we
may have to stop thinking about "how do I multihome in IPv6" and say
"how do I provide reliablity in IPv6".

Of course, there aren't good answers to that question yet.  :(

As far as I know, you have exactly the same multihoming solution
available now as you do with IPv4 - advertise a more specific route.
Since AFAIK IPv6 folks don't filter heavily on prefix length, this
should give you multihoming today as good as with IPv4.

Yes, it's a suckful situation, but no worse than current practice.

I'm not sure what exactly is meant by this.... ???
