I got a problem with setting up ipv6 on a clean installed UCS 4.3 installation.
After adding the ipv6-address, suffix and the ipv6-gateway ipv6 is working. after a reboot ipv6 stopped working.
it seems the ipv6 gateway isn’t added as a default route after a reboot.
trying to set it manually isn’t working either:
ip -6 route add default via fe80::1 RTNETLINK answers: Invalid argument
ucr search ipv6/gateway shows the right gateway.
ipv6-dns resolution still works, it is just the route missing…
even removing and adding the ipv6 address and/or the gateway won’t work.
just manually adding the gateway to /etc/network/interfaces and reloading the networking service helps.
I am a bit puzzled. Am I doing something wrong or is it a bug?
