IPv6 Tracking Interfaces Lose IPv6 Address in Certain Cases

Description

IPv6 assigned to inside interfaces seem to lose their assignments one by one over time upon renewal or interface reset. This seems to only occur if the time necessary to complete the renewal is more than X. It takes a couple of minutes for all of the interfaces to lose their assignments. Seems to be about one every 10 seconds. It also only appears to impact VLAN interfaces, not direct interfaces (vmnet0, igb1).

To test this I installed a new 2.4.4.CE VM and created WAN (vtnet1) LAN (vtnet0) and 10 VLANs on vtnet1 (vtnet1.3501 - vtnet1.3510, OPT1-OPT10).

LAN and OPT1-OPT10 were all configured as Static IPv4, Track Interface, WAN IPv6.

WAN was configured for DHCP, DHCP6, with a /56 Prefix Delegation.

Upon boot, all inside interfaces receive track interface assignments and everything works.

But if you Edit/Save WAN, All interfaces receive track interface assignments but then some inside interfaces drop their address assignments.

As far as I can tell, this occurs when this is logged:

Nov 18 23:34:01 check_reload_status updating dyndns opt9
Nov 18 23:34:01 kernel vlan9: changing name to 'vtnet0.3510'

I am rebooting again to try to watch if it reoccurs on a DHCP6 renewal. That will take some time.

The log messages look the same as #9115, might possibly be the same root cause.

#2 Updated by Dean Attewell about 2 years ago

I also see this, IPv6 static leases disappearing

The fix for #9115 has made this much better but I still see these issues:

Editing/Saving the VLAN parent interface will cause the same issue as originally described. All interfaces receive the tracked prefix assignment then as the VLAN interfaces are reconfigured they lose the assigned prefix one-by-one.

Editing/Saving any VLAN interface causes all VLANs and the parent interface to temporarily lose their IPv6 tracked prefix. After a time they are all reapplied and appear to be permanent.

Jim, could you validate if the problem still happens after fix for #9154 was applied?

I haven't seen this in a while, but cjl saw it more than I did. Reassigning to him for feedback since he could reproduce it easier.

This does not look to be fixed. Created several Track6 VLAN interfaces on vtnet0, a track6 interface on vtnet0, and a track6 interface on vtnet2.

On boot everything looks good.

It looks like any edit/save/apply to any interface wipes all track6 addresses from the interfaces. They reappear a couple/few minutes later. About 2 minutes on this VM.

That is not the absolute end of the world but it certainly could be "better."

Note that all track6 numberings vanish. The parent vtnet0, the VLANs on vtnet0, and the other interface vtnet2.

It looks like dhcp6c is restarting even if the interface changed is not WAN:
