It doesn't. Unless I'm missing on how I can influence e.g. inbound
routing like I can do with BGP announcements, tagged with special
communities to tweak announcement properties (yes/no, prepending
etc.) and things like routing preference ("local-pref" in BGP
semantics) in my upstream's network or even more far reaching than
that. I cannot. And as far as I hear, folks at NANOG (IESG BoF on
IPv6 multihoming) have clearly laid out why shim6 is NOT what we're
looking for - and why. [this is hearsay, I didn't get around to
check minutes and/or slides yet]

As a network administrator I want to define routing properties for
my whole network in a consistent way, not to tweak each policy decision
in each IPv6 stack on each host. The routing policy of a network is
a network property, not a host property. I don't want to HAVE to
control (read: administer!) each and every end device on the network
just to provide proper global routing to it. That's just ridiculous.

That's the basic problem. The IETF folks either don't understand, or
chose to ignore the requirements. There is a nice 6NET document
detailing all requirements and showing a matrix outlining requirements
against proposed solutions. Outcome: NONE except BGP offer a solution
to ALL requirements.

I'm happy to look into any solution proposed that fulfils the needs.
Unfortunately that's not there yet. I'm sure we all would be happy
to get rid of the latent possible danger of BGP.

I don't, as stated.
