But that's the server configuration, surely?  I'm interested in how I
configure the *client* to request a PD and configure one or more
interfaces based on that.  The main problem is: How do I tell the client
that I want to allocate subnet X from the delegated /48 or /56 to
interface I, and subnet Y from the /48 or /56 to interface J?

Bonus for some way to trigger radvd to announce a subnet on one or more
interfaces, and extra bonus for some way to trigger dhclient based on
received RA flags (don't know if that is feasible as long as the
autoconf is done by the kernel?).


The dhclient example doesn't provide much info:

bjorn at nemi:/tmp$ cat dhcp-4.2.0a1/doc/examples/dhclient-dhcpv6.conf 
# Client configuration file example for DHCPv6

# The client side command to enable rapid-commit (2 packet exchange)
##send dhcp6.rapid-commit;

# name-servers and domain-search are requested by default.
# here is the way to request sip-servers-addresses too
also request dhcp6.sip-servers-addresses;

# Likely to be useful: the script path
script "/usr/local/etc/dhclient-script";

That would be great.


This is as far I got:
