I'm trying to make my Ubuntu 16.04.1 home server have (at least) two IPv6 addresses for its bonding interface of two physical network interfaces:
- A static local one from the
fd::range (for a Samba4 primary domain controller). - A dynamic global one, acquired automatically, or assigned by the router (an AVM FritzBox 6360 in my case, from by my cable TV provider Unitymedia).
Of course it should still have a static local IPv4 address.
It used to work no problem about a year ago when I set up a different box, but I'm currently unable to reproduce that.
The problem is that my box does not learn the router's subnet (something in the 20a2:: range), but only has the configured static and an fe80:: address. How to change that? (Detail on my configuration below.)
I'm not intending to use network manager, but /etc/network/interfaces; here's what it currently looks like:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eno1
iface eno1 inet manual
bond-master bond0
mtu 4000
auto eno2
iface eno2 inet manual
bond-master bond0

netmask 64
accept_ra 1
autoconf 1
mtu 4000
bond-mode 0
bond-slaves none
I have installed rdnssd as it is mentioned in the the manpage for the above file in the inet6 section, but I have not changed its default configuration.
Here's the result of ifconfig after rebooting:

Sorry for the german content, but I guess that if you know ifconfig's output, you can still get the relevant information.
My router is currently configured to just assign DNS name server's via DHCPv6, but can as well by configured to additionally assign a prefix (IA_PD), and furthermore an IPv6 address (IA_NA). I've tested all three options - none of them had a recognizable effect.
