I've been using IPv6 connectivity on my residential fibre line for over a year. Telus installed both an Actiontech T3200M and a separate ONT box. Since Oct 25, and the connected power outage in our area (North Delta), IPv6 routing goes down a while (an hour or so) after restarting my router (pfSense). IPv4 is not affected (working).
I searched the forum, and found this thread, which seems to explain what is going on:
This is what I get when I try to ping an IPv6 address:
~# ping -6 www.google.com PING www.google.com(sea09s17-in-x04.1e100.net (2607:f8b0:400a:804::2004)) 56 data bytes From pfsense.localdomain (2001:569:7ef6:9f00:xxxx:xxxx:xxxx:xxxx) icmp_seq=1 Destination unreachable: No route
traceroute dies at my LAN IPv6 address.
The behaviour is the same whether the T3200M is in or out of the chain, which seems to points to a problem with the ONT, or even upstream?
I'm scared of having to call in with a relatively obscure technical issue, so I'm trying my luck here. 🙂
@luca1 I assume the outage was wind related trees down etc. Possible your device had a voltage surge that has weakened something inside. Some devices allow for a reasonable spike some not. Surge voltages can go well over 2 to 300 volt when two hv wires slap together. I think you will require visit from telus unless an online test can be done from telus end . 30 some years power line man. Polecat
Both ONT and T3200 are under an UPS, besides IPv4 is always 100% solid, so I doubt this is caused by something at my place. The IPv6 default gateway route "disappears" from my router's table after a while. I think the problem is with IPv6 Router Advertisement not working properly, much like in the thread I linked.
Somehow the problem fixed itself, after a couple of days. ¯\_(ツ)_/¯ IPv6 default gateway is not expiring anymore.
It would be great if a network tech from Telus would eventually come along an explain the mystery 🙂
