yes, this is redirect that matters, as far as I remember.
(maybe "must not" was too strong, "should not"?)
the adress of ipv6 routers (gateways) are identified by link-local
address, and icmp6 redirect must be sent with source address set with
link-local. for a host to be able to identify its gateway, it needs
to configure all gateway address by using link-local address.
this may not be explicitly written, but for a host/router to work
correctly, it is required.
