Since shim6 requires changes in protocol stacks on nodes, my impression has been that it isn't a _site_ multihoming solution, but rather a _node_ multihoming solution. Is my impression incorrect?
There is no shortage of rough corners to file down, and I am behind on my shim6 mail, but the general idea is to let end sites multi-home in the "bag-o-PA-prefixes" style and let the nodes within that site use their multiple globally-unique addresses (one per upstream, say) to allow sessions to survive rehoming events.
the kicker here is that the applications then need some serious smarts to do proper source address selection.
I suspect will be required is real _site_ multihoming. Something that will take existing v6 customer sites and allow them to be multi-homed without modification to each and every v6 stack within the site.
For end sites, that's a wildly-held opinion.
wildly or widely? :)
