dhcrelay - IPv6 mode - dynamic routing & prefix delegation

[mudrunka at spoje.net]

Hello guys,
ever heard of dynamic routing? like OSPF? etc...

dhcrelay -6 needs "upper network" interface specified, but there is no 
such thing in my network... we've got OSPF dynamicaly routed network 
with cycles and redundant links which means that any interface can be 
possibly "upper". Few subnets away i have DHCPv6 server with static 
unicast (in fact pseudo-anycast) address and i need dhcrelay to 
communicate with this server on any interface where the route to this 
unicast adress will lead.

I just want it to do like i do for dhcrelay -4, that means:

1.) specify interfaces where i want DHCP to be server
2.) specify unicast address of DHCP server (without interface - because 
there is route for it)
3.) profit

Is that possible??? That would be really usefull feature for me 
deploying IPv6 to people.

Another absolutely cool feature would be to check replies from DHCPv6 
server for prefix delegation and if we can ping the DHCPv6 client which 
has been delegated to route preffix, add static route to this prefix via 
this DHCPv6 client (because the prefix will be most likely reachable by 
him).

Maybe this should not be hardcoded, but there should be some option to 
launch custom script on each reply from DHCPv6 server. Then pass DHCPv6 
client IP (eg. link-local) and the prefix in env to this exacutable, so 
i could write script which will try to ping the client and add route if 
successfull...


These two features can make deployment of IPv6 to peoples homes almost 
fully automatic and i've heard that RFCs are starting to head this way 
too...


Thanks

Best regards
