Shim6 does give the end- > user TE capability. 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] > I am not sure what you mean with "network-wide routing policy > implementation".... 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. > I have still to figure out what the "real multihoming" thing is, 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. > >HOW the requirements are being delivered is another topic. multi6 has > >resulted in the decision to ignore many critical requirements.
