[Dibbler] Static DHCPv6 address support

[Burden, Ken]

Hi,

Thanks for the reply.  I had thought of this but wasn't sure if there
was another option.

Next question - I am using a Cisco router to relay the DHCP messages
from another subnet/link to the Dibbler server.  I am seeing errors in
the log file and would appreciate help figuring out what I am missing in
the config file.

Here is my config file.

#
# Note T1 <= T2 <= reconf-grace-period <= plt <= vlt
#

log-level 7
log-mode short

iface eth0 {

# clients should renew every half an hour
 T1 1800
 T2 2000
 prefered-lifetime 3600
 valid-lifetime 7200
 unicast 2001:1890:1109:4:230:6eff:fef2:dc19
 class {
#  accept-only 0001000100d257440014220f5116
   pool 2001:1890:1109:2::40
 }

 option dns-server 2001:1890:1109::10
 option domain vcd.ipv6.hp.com

}

The log file has the following errors:

Also, what is the correct syntax for a DUID for the accept-only
statement?
The PDF file for Dibbler shows 2 sets of quotes for one example but no
quotes for the Link-Local Address example.

Hi,

if you create a class with single ipv6 address in server config and 
set 'accept-only' to link address of your host, it will work as needed:

iface <iface> {
  class { # reserved address for single client:
    accept-only <host_link_address>
    pool <single_address>
  }
  class { #other clients get addresses from here:
    pool <start_address>-<end_address>
  }
}
