I have a configured a bridge and a tap interface on the host system. The tap
interface is bridged with eth1 of the UML.

Subject: [uml-user] Configure UML to work in IPv6 mode
I'm trying to run an UML in IPv6 mode on a Linux (Ubuntu) box, and have not
been successful with it. I could get the UML to boot up alright, but the
interfaces do not
seem to accept IPv6 addresses. The file /etc/config/network looks like
this:
config interface lan
option ifname 'eth1'
option proto 'static'
option ip6addr '2001:220:abcd:70::10/64'
Adding it manually doesn’t seem to help either:
root@OpenWrt:/# ifconfig eth1 add 2001:220:abcd:70::10/64
ifconfig: socket(AF_INET6,2,0): Address family not supported by protocol
root@OpenWrt:/# ip -f inet6 addr add dev eth1 2001:220:abcd:70::10/64
RTNETLINK answers: Operation not supported
root@OpenWrt:/# ip -f inet6 addr add dev eth1 2001:220:abcd:70::10
RTNETLINK answers: Operation not supported
root@OpenWrt:/# ip addr add dev eth1 2001:220:abcd:70::10/64
RTNETLINK
answers: Operation not supported
I referenced a few OpenWRT links that talk about how to enable IPv6 on
the system, and believe I have it in place. Could you please help me
understand what is missing or what is the problem?
I'm not sure what relevant information to provide. Please let me know.
This is what is displayed as the startup banner:
BusyBox v1.19.4 (2013-02-10 13:17:40 GMT) built-in shell (ash)
