Whoa there. The NANOG community (as well as other ISP communities) is hugely
affected by shim6.
They are the ones who will be fielding customer calls about multihoming -
"why can't I just setup BGP like I always have done?". Not everyone at NANOG
is going to be big enough to get a /32, but most of the ISPs there are at
least multihomed today.
I for one am looking forward to both the BoF and Jason Schiller's general
session topic.
I think most of the ISP who are seriously thinking about IPv6 have to have
the ability to have a multihoming solution - getting PI-like address
(nowadays it is /32). For end-systems/customers/enterprises might agree
with upstream providers to accept more specific (and upstream can agree to
exchange more specific inside country/region, but announce aggregate to
global Internet) or use RFC3178 method (using tunnels) which is quite
powerful technique. Any method can be implemented with careful BGP routing
policy configuration.
The shim6 is attractive method, but requires changes in host and router
IPv6 implementations and this requires at least 5 years to be widely
accepted....
Shim6 can be a long term solution, but shorter time-frame the
operator/provider/user community can use existing methods to support/use
multihoming. We can strart using it and if there is some problem we can
speak up at NANOG/RIR etc meetings.
