Hello there,
My ISP (KPN business in the Netherlands) provides ipv4 and ipv6 internet connectivity over pppoe. The pppoe interface gets assigned a public ipv4 address, as well as remote and local link-local ipv6-addresses. My local address changes every time.
The ISP routes a fixed /56 prefix over this connection, which I have to configure manually. I did this by creating a new interface, assigning the first address of the prefix to that interface, and setting the prefix as the ip6prefix. I did not configure a IPv6 gateway for the interface, as the local address changes every time I reconnect. Instead, I added a static default route via the pppoe interface (without specifying the address of the next hop).
The configuration works - however, the interface will not configure itself properly upon a reboot. It will not assign its ::1 address, nor the prefix - even though it is configured to be brought up on boot. When I restart the interface manually (by pressing "restart" in luci), it will configure itself and will work properly.
Any ideas what I can do to make the interface configure itself properly on reboot? Relevant configs/logs below.
Thanks much,
Rien
My relevant openwrt network configuration is as follows:
>
> config interface 'WAN_KPN'
> option proto 'pppoe'
> option device 'eth3'
> option username 'internet'
> option password 'internet'
> option mtu '1500'
> option metric '1'
> option ipv6 'auto'
>
> config interface 'WAN_KPN_6'
> option device 'pppoe-WAN_KPN'
> option proto 'static'
> option ip6prefix '2a02:22a0:XXXX:XXXX::/56'
> list ip6addr '2a02:22a0:XXXX:XXXX::1'
> option defaultroute '0'
> option metric '0'
> option force_link '0'

> ...

> config route6
