Default Gateway Switching for IPv6 GW
« on: March 14, 2014, 09:29:56 am »
Is Default Gateway Switching for IPv6 supposed to work? It won't work on my setup. IPv4 gateways are switched, when WAN1 goes down. IPv6 gateways are not.
I'm using DHCPv4 on the WAN1 GW with a HE.net Tunnel build upon it, those are both shown as down when I pull the network cable from my cable modem. WAN2 is static IPv4 and static IPv6 behind another router. The IPv6 static route points to the Link-Local address of the other router.
netstat -arn shows that the IPv4 gateway is switched to WAN2 while the IPv6 default GW stays with the non functional giftunnel.
The logs says:
Code: [Select]
php: /index.php: The command '/sbin/route change -inet6 default fe80::c225:****:****:890e' returned exit code '1', the output was 'route: writing to routing socket: Network is unreachable route: writing to routing socket: Network is unreachable change net default: gateway fe80::c225:****:****:890e: Network is unreachable'
