Upgrading from 2.6 to 2.7 breaks HE GIF tunnel?
-
GIF/OPT1 interface no longer has IP address assigned and cannot ping the public IP6 externally. How can we restore this functionality?
ping6 -I gif0 2001:xxx:xx:xxx::1 from the CLI works to ping the remote tunnel endpoint, but the gateway status still shows pending on the dashboard.
Disabling gateway monitoring and gateway monitoring action brings the gateway up on the dashboard but does not further enable connectivity. ping6 -I gif0 google.com still results in 'No route to host'.

I do also have a 2nd IPv6 interface via WAN instead of OPT1 provided by google fiber which now seems to be stable - before it kept going down every 30 minutes and typically required a reboot to fix. In case this is also relevant to the HE tunnel no longer working as it should. I require the HE tunnel for my static IPv6 addresses as well as my reverse DNS.
Deleting the default route to 2001:xxx:xx:xxx::1 and readding seems to restore connectivity via the GIF tunnel, breaking the GF ipv6. GF ipv6 is quickly restored seemingly automatically and the GIF is now broken again.
Nuked the GF ipv6 config and reinput. Set default ipv6 gateway from automatic to the GIF tunnel. Both GF and HE are working at the moment.

Does the interface not show an address in the GUI or also at the CLI with
ifconfig?Can you use the system patches package and try reverting
c5d786359cc4a15c81e1c4773ab271b3d49ed594and then revert3222c70aaf783336901f7b1225727b5973ba865ato see if the behavior changes?If there is no change in behavior you can reapply them.
