1) Ability to indicate to a host "DHCP is not available on this link",
with the expectation that the host won't send any DHCP messages
1') Some people (one person?) also wanted the ability to indicate
to a host "a particular type of DHCPv6 (i.e., ICB or HCB) is not
available on this link" (This is probably a combination like
M=0&&O=1 would currently indicate)
2) Ability for a host to get all desired and available DHCP
configuration with a single DHCP message exchange
- if a host wants HCB, it sends an HCB request (Solicit) and receives
HCB and/or ICB replies
- if a host wants ICB, it sends an ICB request (Information-request)
and receives ICB replies
3) Ability to do DHCP without having to configure routers
(e.g., by ignoring RA with M=0 and/or O=0 and invoking HCB and/or
ICB anyway)
Are 1) and 3) mutually exclusive, or is the requirement to have some
M/O combination that says "There is no DHCP, do not try to find it"
and another combination that says "I make so representation about the
DHCP status so you're free to have a look for it"? Or have I completely
missed the point?
