Re: Shim6 vs PI addressing

Please don't mix up addressing and routing. "PI addressing" as you mention is addressing. SHIM6 will become a routing trick.I think that is overly pessimistic. I would say that SHIM6 _MAY_ become a routing trick, but, so far, SHIM6 is a still-born piece of overly complicated vaporware of minimal operational value, if any. Personally, I think a better solution is to stop overloading IDR meaning onto IP addresses and use ASNs for IDR and prefixes for intradomain routing only.
Full ACK! For the IDR we then can use perfect match lookups which scale very well and pretty cheaply to many millions of table entries. BGP scales very well too if you've got a decent cpu in your router. Our OpenBGPD easily does 30 flapping constandly full-feeds with 1 million routes each. Lets get pragmatic and realistic! -- Andre
