FS#2417 - Maybe it's a new bug on odhcpd with 6in4

Just now, I found a bug that made odhcpd unable to add expire time to subordinate devices.Maybe it’s just a coincidence, but I think it’s better to report it first. As shown in the title, this bug should only occur in a network environment using 6in4. My broadband operator may be forced to go offline at any time, I don’t know what the reason is. So sometimes I wake up and find that there is no IPv6 network. The update scripts are not good enough, at least for me. So I am manually updated by chance.

It should happen on all devices but I don’t have so many devices to test so I only tested it on my PHICOMM PSG1218 Ver.A .

After the 6in4 network is unavailable for a long period of time, when the odhcpd sends the IPv6 network to the lower-level device. It has a certain probability that the signal will be sent only once. After the lease time, there is no signal. But after restarting the odhcpd software, everything is fine. The configuration is the same as before, there is no change, so I think it should be a bug...

Maybe more examples are needed to prove this bug, but I will mark it first.

Based on the provided info it's impossible to make any conclusions.
You will have to provide more info for trouble shooting.
As a starter you can check the odhcpd traces (by setting odhcp loglevel to 7) and ifstatus of the lan and wan interfaces
