Hi Zach,

Thanks for this new version.

I still have a comment about section 5.3.
In this section one can read that the RS must (actually there is no MUST, 
SHOULD, MAY in the text) be sent to the IPv6 All-Routers multicast address 
and the destination link-layer address may be some kind of all-routers 
anycast link-layer address.

However in section 10.2 the 2nd element of the list says that the RS can 
be sent unicast to the router with its link-local IPv6 address.
Don't you think that section 5.3 should mention the possibility to send a 
unicast RS in addition to the example provided in section 10.2?

Best regards,
