Hi,

I am trying to setup IPv6 routing, but it is broken after every reboot, as the mac address of a configured bridge is constantly changing.

vmbr1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 82:71:8a:73:9d:51 brd ff:ff:ff:ff:ff:ff
inet6 fe80::8ca4:24ff:fe97:d171/64 scope link

Also, the LLA does not seem to be derived from the MAC address?

What can I do to fix this? I need a static Link-Local-Address.
