Re: support for reconfigure for prefix delegation?

Doesn't work... :(

So I've now added "noauthrequired" at the top of my /etc/dhcpcd.conf.

Then I've restarted the dhcpcd service unit and checked using Wireshark that I correctly see the prefix delegation getting leased with a Solicit/Reply message pair. Then I tell my Fritz!Box to reconnect its WAN link. Next I see the Fritz!Box correctly sending a Reconfigure message.

DHCPv6
    Message type: Reconfigure (10)
    Transaction ID: 0x000000
    Client Identifier
    Server Identifier
    Reconfigure Accept
        Option: Reconfigure Accept (20)
        Length: 0
    Option Request
        Option: Option Request (6)
        Length: 8
        Value: 0019005200530043
Requested Option code: Identity Association for Prefix Delegation (25)
        Requested Option code: SOL_MAX_RT (82)
        Requested Option code: INF_MAX_RT (83)
        Requested Option code: Prefix Exclude (67)
    Reconfigure Message
        Option: Reconfigure Message (19)
        Length: 1
        Value: 05
        Reconfigure message type: Renew (5)

But dhcpcd does not start a renew, no DHCPv6 messages seen.

Anything I'm forgotten to configure? I've rebooted to be sure, but still no reaction to the reconfigure message.

Best regards,
Harald

Yes, Roy, your answer is helpful!

My wireshark packet captures show no sign of any OPTION_AUTH(11). In
fact, the AVM Fritz!Box sends the reconfigure without it:

Is there a way to configure dhcpcd to accept unauthenticated
reconfigures?

noauthrequired is documented in dhcpcd.conf(5)
