DM7080 OE 2.5 tries to aquire a DHCP6 address every 2 seconds

  • I am using the latest OE 2.5 image on my DM7080.
    When I enable IPv6 as auto in the network setup, it works and aquires an address using DHCP6.
    But then it continues to send a DHCP6 request every 2 seconds, even though the lease time is much larger (12 hours).
    I see the following messages on my OpenWRT router:


    OE 2.5 seems to send a SOLICIT message every 2 seconds to find routers, followed by a REQUEST message to get configuration information.
    Why is this done every 2 seconds, even when the router includes a life-time in the response?


    Is this a know problem?

  • Am I correct in assuming the udhcpc is used to obtain IPv6 leases or is this only used for IPv4?
    Is there a configuration file or setting I can check or change to verify the lease renewal time?
    Renewing a lease every 2 seconds seems clearly wrong in my opinion.
