Mathieu,
In that case I believe the DHCPv6 server implementation in your router
differs from the one I use on my network (dhcp-4.1.2-4.ESV.R2.fc13.i686
on Fedora 13). My DHCPv6 replies never contain any DNS information
unless explicity requested by the client, while I understand yours
always does.
I've looked through the client system but I cannot find any
dhclient.conf file there. However, the dhclient.conf manual page differs
significantly - I cannot find any mention of this "send dhcp6.oro"
statement at all. However, what relevant stuff I do find, says the
following:
The request statement
[ also ] request [ [ option-space . ] option ] [, ... ];
The request statement causes the client to request that any server
responding to the client send the client its values for the specified options.
Only the
option names should be specified in the request statement - not option
parameters. By default, the DHCPv4 client requests the subnet-mask,
broadcast-
address, time-offset, routers, domain-search, domain-name,
domain-name-servers, host-name, nis-domain, nis-servers, ntp-servers and
interface-mtu options
while the DHCPv6 client requests the dhcp6 name-servers and
domain-search options. Note that if you enter a ´request´ statement, you
over-ride these
defaults and these options will not be requested.
So it appears this particular implementation/version will by default
request the necessary options. The dhclient binary is found in the
package dhclient-4.2.0-21.P2.fc14.x86_64.
Let me know if you need any more help!
Tore
