## Assumptions

You have a computer with at least a /64 network routed to it.



## Architecture

bridge, radvd,


## Configure LXC


[root@diamond ~]# cat /etc/lxc/default.conf
#lxc.net.0.type = empty
lxc.net.0.type = veth
lxc.net.0.link = brlxc
lxc.net.0.flags = up


## Create a bridge


## Configuring radvd

```
interface brlxc
{
  AdvSendAdvert on;
  MinRtrAdvInterval 3;
  MaxRtrAdvInterval 5;
  AdvDefaultLifetime 10;

  prefix 2a0a:e5c1:137:cafe::/64 {
  };

  RDNSS 2a0a:e5c0:2:1::5 2a0a:e5c0:2:1::6  { AdvRDNSSLifetime 6000; };
  DNSSL nicotest.ungleich.ch {  AdvDNSSLLifetime 6000; } ;
};
```
