Interested in DHCPv6?

Fri Jun 30 16:04:58 UTC 2006

ok then.... I feel weird about this response because it's not ISC's 
software.....
Yes we use it.... in the lab for testing, 

we use a couple of FreeBSD 5.5 machines with kame snap from earlier this 
year,   cisco router (3560 IOS 12.3 or later) in the middle for relay 
support testing  (mbit on = 1, but no prefix advertisement on the router)
We were told by Cisco tech support they would support the relay agent on 
our 7600 by August 2006.  So we are using the 3560 now because it supports 
the IPV6 relay agent.

We use the dhcp6s from the Kame project, of course this is a static 
address assignment, not utilizing a pool, and there is no lease timeout. 
(keyword infinity)
 it's config file is.... 

# The following are a sample configuration to provide a DNS server address
# for every client as well as to delegate a permanent IPv6 prefix
# 2001:db8:1111::/48 to a client whose DUID is 00:01:00:01:aa:bb.

option domain-name-servers 2001:1234:0:1::2;

interface de0 {
        allow rapid-commit;
};

host windows {
        duid 00:01:00:01:0b:f3:9a:96:00:06:5b:bd:50:4b;
        prefix 2001:1234:0:3::/64 infinity;
        address 2001:1234:0:3::103 86400 ;
};

*** The client setup for dhcp6c is the following  ***

id-assoc na 1 {
};

interface fxp0 {
        send ia-na 1;
        send rapid-commit;
};

***An ethereal sniff from the client shows the following... packet 
sequence***

I don't know about the rest of the list, but I'd certainly like to
hear about DHCPv6 servers and any challenges or problems that people
have faced.  We're looking at doing a DHCPv6 server at some point,
so if there's already some operational knowledge I'd like to hear.

I don't think there's any reason to switch off-list at any rate.
