Rich, Dave, Quick comment/question on the router selection spec.
When a parameter is changed (e.g. the operator changes the default router preference or adds a route option) what should the router do? I guess it's implicit it should do the same as [RFC2461,6.2.4,last para] i.e. as for "becoming an advertising interface". If so, could this be made explicit? When a router interface is going down: [RFC2461,6.2.5] currently says (roughly) "SHOULD transmit one or more RAs with Router Lifetime zero". I'm uncertain if this would clear a ::/0 route in a type C host - the text currently says "updates a ::/0 route ... based on the Router Advertisement message header". Does "update" encompass "delete"? Also, such a final RA wouldn't clear any more specific routes. Does the latter case need some more text e.g. "SHOULD send all more specific routes with lifetime zero" or somesuch? Thanks.
