Hi Brian(s);
My concern is the scenario where an operator knowingly disables
prefix advertisements and enables DHCPv6. If the nodes doesn't
do DHCP, it is stuck with only the link-local address.
Understood. That certainly deserves a health warning. But in large
scale deployments of low-end devices, implementors need to feel
free to leave DHCP out.
Just a small comment - 2462 (stateless aa) is a MUST. Additionally,
manual configuration is always a possibility as well. If certain
hosts know they don't need DHCP, then I don't see the problem of
having DHCP as a MAY.
In general, stateless address autoconfig is a good thing, so we want
to encourage service providers to do the right thing.
Maybe the right thing is to attach a warning or an explanation
about the implications and leave the support as a MAY. For
instance,
"Nodes that do not implement DHCP may become unable to
communicate outside the link when their routers advertise
stateful autoconfiguration and no prefixes suitable
for stateless autoconfiguration are offered."
