dhcpv6 server and dhclient IA_PD support

[Aaron Murrihy]

Hi Kunal.

I asked this exact same question on this mailing list a couple of
weeks back, but unfortunately no answer was able to be provided.

Let me outline the fruits of my labours thus far:
In the man pages where it says that "option dhcp6.ia-pd" is not
implemented is an error, it actually has. This has been fixed in the
4.2 beta.
I have been unable to discover a way to bind a prefix (or address) to
another interface on the device. It seems an odd feature to not have.
WIDE DHCP has a very simple config option for doing this.

This is an example of the server config I am using to delegate a prefix:
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet6 2001:db8:0:1::/64 {
       # Range for clients
       range6 2001:db8:0:1::129 2001:db8:0:1::254;
       # Prefix range for delegation to sub-routers
       prefix6 2000:1:1:100:: 2000:1:1:f00:: /56;
}

You just have to request a prefix using the client's -P option.

Anymore questions don't hesitate to ask either using this mailing list
or my personal email address.

Also might I ask if you have any breakthroughs in this area to let me know?

Cheers
Aaron

How would the dhclient configure different subnets on different interfaces (for simplicity's sake, lets consider just one subnet for one interface) from the prefix delegated by the server ?
