IPv6 Errors in logs
-
I keep getting the following over and over again in my routing log:
Jun 15 22:23:48 radvd 62177 our AdvPreferredLifetime on em0 for 2604:5500:c078:8000:: doesn't agree with fe80::768e:f8ff:fea6:6e01
Jun 15 22:23:48 radvd 62177 our AdvValidLifetime on em0 for 2604:5500:c078:8000:: doesn't agree with fe80::768e:f8ff:fea6:6e01
Jun 15 22:23:48 radvd 62177 our AdvOtherConfigFlag on em0 doesn't agree with fe80::768e:f8ff:fea6:6e01
Jun 15 22:23:48 radvd 62177 our AdvManagedFlag on em0 doesn't agree with fe80::768e:f8ff:fea6:6e01em0 and associated ipv6 ranges are on my WAN interface.
This has been happening for months now, but IPv6 seems to be working just fine.
Using Track interface, with /56 prefix. Router mode is set to managed in case that's relevant.
Any ideas, suggestions?

@mgittelman what is the device on your network with ip address fe80::768e:f8ff:fea6:6e01? Is it possibly also running radvd? I had this same error and found my wireless access point running DD-WRT had IPv6 enabled and was running radvd. Disabling radvd on the access point resolved the conflict.

Thanks, I thought about that, but the address in question is clearly listed as my WAN gateway:
IPv6 Address
2604:5500:c078:8000:xxx:xxxx:xxxx:xxxx
Subnet mask IPv6
64
Gateway IPv6
fe80::768e:f8ff:fea6:6e01The only other device I can think of that could possible run misc network services would be my Aruba AP whose IP doesn't match.
I have no other router on my LAN.
