Description

I have 2 PPPoE WANs at home and IPv6 only works on primary link, used as default gateway. In this case pppoe0 works as expected and pppoe1 fails because system tries to route its gateway address through pppoe0 connection. ifconfig show it as detached.

[23.01-RC][root@pfgarga.home.arpa]/tmp: ifconfig pppoe1
pppoe1: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492
