 ### Configuration Files
 
 1. On Debian/Ubuntu systems, an entry in "/etc/network/interfaces" can be used to statically assign the ::1 address for the local LAN. Example:
-         iface eth1 inet6 static
-                 address 2001:db8:beef::1::1
-                 netmask 64
-                 mtu 1280
+       iface eth1 inet6 static
+       address 2001:db8:beef::1::1
+       netmask 64
+       mtu 1280
   On non Debian/Ubuntu systems, a line can be put in a boot script, such as "ip -6 addr add 2001:db8:beef:1::1/64 dev eth1".
 
 2. IPv6 forwarding needs to be enabled: put "echo "1" >/proc/sys/net/ipv6/conf/all/forwarding" in a boot script, or "net.ipv6.conf.all.forwarding = 1" in "/etc/sysctl.conf".

 4. It is assumed that the config files go into something like "/etc/tinc/link" and "/etc/tinc/nets.boot" has an entry for "link". The following table can be used to guide configuration of routers:
   * "routera" configuration for tinc (the master router):

 5. You can use [radvd](http://www.litech.org/radvd/) or [Quagga](http://www.quagga.net/) to perform [stateless address autoconfiguration](http://www.ietf.org/rfc/rfc2462.txt) on your LAN. This is an example zebra.conf for LAN autoconfiguration (don't forget to enable the zebra daemon):
