I just told my router to send log entries to a computer on my lan, and it is talkative:
<3.4> 2016-03-19T20:24:50+01:00 router radvd 675 - - our AdvOtherConfigFlag on br0 doesn't agree with fe80::8cae:84ff:fe43:27d4
You have more than one device, that sends router advertisements or dhcp answers. See man radvd -> AdvOtherConfigFlag on|off
When set, hosts use the administered (stateful) protocol for autoconfiguration of other (non-address) information. The use of this flag is described in RFC 4862.
and i think the flag controls how RFC 4862 section 5.6 is managed.
Ah, it is starting to make sense! Kind of. I do have two routers, yes. One is the actual router, connected to my ISP fibre, the other is only acting as a WiFi access point, not as router (its WAN is disconnected).
But the IP that the message is reporting, fe80::8cae:84ff:fe43:27d4, happens to belong to my switch, not the router.
No, according to neighbor information you sent it is your wireless AP:
Telcontar:~ # ip neighbour show fe80::8cae:84ff:fe43:27d4 dev eth0 lladdr f8:1a:67:91:f4:22 router DELAY 192.168.1.5 dev eth0 lladdr f8:1a:67:91:f4:22 STALE <==== wifi AP.
ISP--fibre--[Main router]---[switch]---[R-W-A.P.]--
My computer is connected to the switch.
On the "Router-WiFi-Access Point" I have dhcp disabled on IPv4. However, it is impossible to disable RADVD, which is used for IPv6, and is the culprit here.
The configuration page says (TD-W8970):
+++...................... IPv6 LAN Settings
The parameters of IPv6 LAN can be configured on this page.
Note: Only default group supports IPv6 now.
Group: Default Address Autoconfiguration Type: (*) RADVD () DHCPv6 Server
What happens if you change it to "DHCPv6 Server"? I expect it to stop sending RA.
