Title: General question in SLACC ,DHCP
Post by: Ahmed M. H. Alzaeem on March 31, 2014, 01:32:56 AM
hi all ,
i have a question here
if i have a windows 7 , and i configured static ipv6 on it ,
there is no need to ask for M , O flags .

is that correct ?

Q2-now , if i put on my windows 7 pc to get the  ip from dhcp ,
i want to ask ,
who will tell the pc to get it by statefull or statless ???
i mean if there wasnt a router  and there was only pc and dhcp server.

how will the pc get the ip by dhcp ?
will it use slacc only ?
or it will get ip from dhcp server? state-full or stateless?

regards

Yes

Does this help answer your other questions?  (Yes, I know it's Vista, but it's similar)

What does any of this have to do with IPv6 Certification? Might need to get moved to the proper topic/forum.

A1: if you use static IP assignments, DHCP/RA flags are pointless and it won't use them if available and their DHCPv6 client is disabled.

A2: you can't run DHCPv6 without a router, as something has to use RA to advertise Management and Options flags. Otherwise the client won't know to use DHCPv6. Think about DHCPv6 versus SLAAC (and what SLAAC stands for) and that should be a pretty obvious answer for stateful/less

A3: If the client has DHCPv6 support, the M flag in the packets direct it to request the IP from the DHCPv6 server, and O tells it there are available options, like IPv6 recursors.
