dhcpcd-discuss

Hi,

my setup is as follows: a Fritz!Box 7490 with recent firmware as my 
delegating IPv6 router for PD. On the client side on a requesting router 
for PD, I'm using dhcpcd 6.7.1 on Raspbian Jessie. The requesting router 
is asking for a single /64 PD for its own downstream interface, which it 
gets without any hassle.

Now, when the Fritz!Box gets a new prefix block (I'm getting /56's), 
then it sends a unicast reconfigure DHCPv6 message to my requesting 
RasPi router. However, as I see from my Wireshark trace, dhcpcd does not 
seem to react to the reconfigure message. Instead, it waits for T1/renew 
to pass, then gets its renew attempt denied, and starts over with fresh 
soliciting.

Can I configure dhcpcd to accept reconfigure messages from its DHCPv6 
server? I could not find any configuration option, but then I might have 
missed it. If reconfigures are supported, what configuration do I need?

With best regards,
Harald
