DHCP in the context of IPv6 (except for PD) is only used if you want to set the client DNS automatically, but in order for the client to go to the DHCP server you need to set the managed bit to the RA messages. Hope this clears things a bit. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
