 ### 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
-  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".

 3. This setup uses tinc's "switch" mode: subnets are not assigned in the host files; only Address (for ConnectTo targets only) and the key are required in host files.
 
-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):
-	 >cat tinc.conf
-	 Name = routera
-	 Mode = switch
-	 Interface = vpn6
-	
-	 >cat tinc-up
-	 #!/bin/sh
-	 #Enable tinc
-	 ip -6 link set $INTERFACE up mtu 1280 txqueuelen 1000
-	 ip -6 addr add 2001:db8:beef::1/64 dev $INTERFACE
-	 ip -6 route add 2001:db8:beef::/48 dev $INTERFACE
-	 #Static routing table
-	 ip -6 route add 2001:db8:beef:2::/64 via 2001:db8:beef::2
-	 ip -6 route add 2001:db8:beef:3::/64 via 2001:db8:beef::3
-	 ip -6 route add 2001:db8:beef:4::/64 via 2001:db8:beef::4

-	 #Static routing table
-	 ip -6 route del 2001:db8:beef:2::/64 via 2001:db8:beef:::2
-	 ip -6 route del 2001:db8:beef:3::/64 via 2001:db8:beef:::3
-	 ip -6 route del 2001:db8:beef:4::/64 via 2001:db8:beef:::4
-	 #Disable tinc
-	 ip -6 route del 2001:db8:beef::/48 dev $INTERFACE
-	 ip -6 addr del 2001:db8:beef::1/64 dev $INTERFACE
-	 ip -6 link set $INTERFACE down

-  * "routerb" configuration for tinc (the other non-master routers will be like this one):
-	 >cat tinc.conf
-	 Name=routerb
-	 Mode = switch
-	 ConnectTo = routera
-	 Interface = vpn6

-	 >cat tinc-up

-	 ip -6 link set $INTERFACE up mtu 1280
-	 ip -6 addr add 2001:db8:beef::2/64 dev $INTERFACE

-	 ipv6 forwarding
-	 !
-	 interface eth1
-	  no ipv6 nd suppress-ra
-	  ipv6 address 2001:db8:beef:1::1/64
