I did a complete new install and used Linux bridge. The problem is that I can not set the IPv6 address.
The configuration is pretty simple:

Code:
auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

iface enp10s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address  10.0.0.8
        netmask  24
        gateway  10.0.0.1
        dns-nameservers 10.0.0.1
        dns-domain intra
        bridge-ports enp10s0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

iface vmbr0 inet6 static
        address  fd00::8
        netmask  64

auto vmbr9
iface vmbr9 inet manual
        bridge-ports eno4
        bridge-stp off
        bridge-fd 0

After reboot the vmbr0 interface has the Ipv4 address and does accept addresses via RADV but it does not set my fixed IPv6 address:

Code:
7: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 00:02:c9:53:96:fc brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.8/24 brd 10.0.0.255 scope global vmbr0
       valid_lft forever preferred_lft forever
    inet6 2003:f4:73cb:1900:202:c9ff:fe53:96fc/64 scope global dynamic mngtmpaddr
       valid_lft 279sec preferred_lft 129sec
    inet6 fd00::202:c9ff:fe53:96fc/64 scope global dynamic mngtmpaddr
       valid_lft 604779sec preferred_lft 86379sec
    inet6 fe80::202:c9ff:fe53:96fc/64 scope link
       valid_lft forever preferred_lft forever

Any idea why it does not accept the address?
 
Could you solve your problem in the meanwhile? Your configuration looks OK and worked for me. Is it possible that RADV has overwritten your manually set address or something similar?

Thanks for asking. I did not make it working but continued to use Open vSwitch. OVS is working as expected.
