Hi,
A could of quick comments on draft-daniel-ipv6-ra-mo-flags-00.txt.
Editorial suggestion: please switch to use XML2RFC. Pretty please!
Two bigger issues:
1) This document doesn't seem to take a stance what happens when/if the host
has multiple routers (whether on the same or different interfaces), and some
of them have O/M bits set and some others not. Would that lead to a
set-unset-set-unset loop, with triggering? If heard on another interface,
should that affect how DHCPv6 is run?
2) The treatment of M/O flag "transitions" and the initial state after a
reboot is not 100% unambiguous.
In section 6.0 you said:
The host should reset these flags depending
on the information received in RAs when the host is rebooting.
...
Policy 2: The host SHOULD invoke Stateful DHCPv6 for address
autoconfiguration (along with other configuration information)
if and only if it sees an RA changing the M bit from unset to set.
==> but in previous sections, you used the wording "from unset to set";
this requires that there is, in fact a transition -- that these are always
initialized to zero.
The latter wording ("RA changing the M bit") is also confusing because
"M bit" has typically been considered as a property of the routing
advertisement, not a global variable of the node.
