Multi WAN and ipv6

[marjohn56]

Actually nothing is 100 % correct when I said this was 100% working. After a reboot, I have a race condition and the IPv6 doesn't immediately show up on the xDSL link. I need to manually go in Interfaces > Overview and Reload the xDSL link in order to have an IPv6 address. Any idea to avoid this manual step at each reboot?

Are you seeing the requests being sent in the log?


As a side note I used to get exactly this issue with Sky UK after a reboot. No release was sent at reboot ( if it was set to send no release )  or hard power off. Then when it sent a new request after coming back up their BNG would not respond as the XID was now different. The only way to get the v6 address back was to power down the modem completely and wait 30 minutes, turn it back on and hey presto; this was because the lease timed out after 30 minutes and the BNG would then listen again... another reason I changed ISP!

Nope. I'm not. As if the link wasn't ready to receive RA paquets when dhcp6c is being launched. This really sounds like a race condition.

From my side, I'm not aware of any BNG issues (and the need to wait to request IPs again) like you described with both of my ISPs, so I don't think this comes from this point. Actually my ISP are still quite open in the sense I could request several IPv4 or IPv6 prefixes and they are not complaining.

Is there anything from dhcp6c in the logs when the condition occurs?
