IPv6 Neighbor List : Status : failed

Hi there.

I've a strange problem that I don't really understand.

My IPv6 setup works for a few minutes, and then, at the next ND I suppose, the physical interface with the ipv6 connection goes to "failed" in the Neighbor List. If I disable/enable , it's working again for a few minutes, and then boom again.

It's the "ether7" in this situation :

0 R address=fe80::ba0:bab interface=vlan832-orangeV6 mac-address=A0:F3:E4:54:E7:8E status="stale"

1 address=fe80::80d8:6ee9:91d4:d842 interface=ether5 mac-address=C0:3F:D5:6F:71:45 status="stale"

2 address=fe80::6cae:7ee4:2ae7:82ee interface=ether5 mac-address=38:2C:4A:6D:E8:43 status="stale"

3 address=2a01:cb00:[...]:6a4e:4f60:6eba interface=ether7 status="failed"

4 address=fe80::c2ee:fbff:fef8:6330 interface=ether5 mac-address=C0:EE:FB:F8:63:30 status="stale"

And when the status is failed, the mac address in the Neighbor list is 00:00:00:00:00:00. I disabled the ipv6 firewall, same thing...

For the record, eth5 is the lan side, ethernet7 is wan, but vlan832-orangev6 is the "logical" interface linked to eth7.

8 DL fe80::e68d:8cff:fe3d:5d7b/64 ether7 no

I really don't get why it's working for a while, and it's like, the first discovery is "wrong" and this interface goes into failed status...

Same problem. But with OS when they launched on some hypervisors and they have connect to lan via WiFi

Good morning, old topic here.

Any progress?

I am facing same issues with several hosts.
