DHCP(v6) rebind fails after carrier loss #314

So it looks like IPv6 is not started due to the LL address being absent. |

Hi,
I am running dhcpcd (10.0.6-r2) on gentoo linux router connected to a DSL link (dsl modem as a bridge), WAN v6 prefix provided using SLAAC, (static) LAN v6 prefix delegated using DHCP-PD. Once the DSL links loses carrier, dhcpcd does not recover once carrier up again, please see the logs below.
dhcpcd rebind fails, it needs 'dhcpcd -k' prior dhcpcd rebind works.
Cheers,
Ales
