Another option is to include a PVD option, and try to add a boot-url key to
the PVD info in the PVD server reply.

wow, I haven't seen this! I'm following up with the authors right now to<br>
find out what the status was/is.<br>

A quick look into it shows that it is probably about 85% overlapping<br>
with our proposal, with the difference of the reserved fields and the<br>
padding proposal.<br>
<br>
I personally would also *not* advocate to support individual nodes<br>
configuration, to keep the routers stateless, which is in my opinion<br>
still one of the biggest advantages of RA vs. DHCPv(4,6).<br>
<br>
