This aspect isn't nailed down yet, but basically there are two
options: depend on the application do try all addresses (which apps
should do anyway, but I for one wouldn't want to wait for all these
timeouts), or have the shim detect that the first address doesn't work
and repair the failure. This adds additional complexity, though, and
there is still a timeout, although it isn't a full TCP SYN timeout.

Mmmm, DNS load balancing. As a shareholder in my current employer, I
am happy to see that market increase. As a network engineer, I keep
getting the feeling I'm missing out on some great drugs.
Or, on top of that, how traffic engineering can be performed with
For outgoing traffic there is no difference with the current situation
(as long as there are nog ingress filtering issues). For incoming
traffic, it basically starts with DNS load balancing, and the shim
itself will have priority mechanisms to choose between different
address pairs but this will generally not come into play because the
idea is that the shim doesn't do anything unless there is an outage.
So where were you the past years in multi6 and months in shim6? Please
be part of the solution and not part of the problem. (That goes for
John Payne and Daniel Senie too.)
I was in denial that multihoming would get this broken. I've joined
the mailing list... I'll note that the mailing list archive is not
linked anywhere useful, so to save others the guesswork:
