This is not what I think of when I say "multihoming". I don't see
an easy way to do this with shim6 (there may be a non-easy way,
though) so maybe hosting companies that are big enough to do
peering will need to continue to do this as in IPv4.
Couldn't this be implemented into the resolving DNS, in that it
could include priority information into the DNS response sent to
the host that does the initial connect? Or it could be done via
reverse-DNS (in the case where the "called" party needs to know
which IP to send to when there are several to choose from)?
this is pretty much SRV records.
Perhaps one state in the shim6 initiation could be to do reverse-
lookup and via some record there gain knowledge about which IP
should be prioritized? This means that routingpolicy needs to be
somehow implemented into the DNS server, which would require new
code there as well.
Then you need secure binding beetween forward and reverse DNS. Which
just isn't there.
