+==== Initial Steps to setup the Bridge =====
+
+Open the terminal on Ubuntu.
+
+IPv6 forwarding must be enabled before running the bridge sudo nano /etc/sysctl.conf
+Uncomment the line which contains:
+
+net.ipv6.conf.default.forwarding=1
+
+Reboot / logout and login back on the system
+
+==== Build a bridge =====
+
+1. Disable the WLAN before building the bridge.
+
+2. First you will need to program a TelosB/Tmote Sky, or similar node with a IEEE 802.15.4 compliant bridge. The bridge is available in contiki-2.4/tools/sky/uip6-bridge/uip6-bridge-tap.c and you upload the code with the following steps:
+
+* $ cd contiki-2.4/tools/sky/uip6-bridge
+* $ make uip6-bridge-tap.upload
+
+3. Install radvd in your Ubuntu Linux
+* $ sudo apt-get install radvd
+
+4. Create a file /etc/radvd.conf and copy the following lines to that file
+
+interface tap0 {
+     AdvSendAdvert on;
+     AdvLinkMTU 1280;
+     AdvCurHopLimit 128;
+         AdvReachableTime 360000;
+         MinRtrAdvInterval 10;
+         MaxRtrAdvInterval 15;
+         AdvDefaultLifetime 45;
+                 prefix aaaa::/64
+     {
+         AdvOnLink on;
+         AdvAutonomous on;
+         AdvPreferredLifetime 4294967295;
+         AdvValidLifetime 4294967295;
+     };
+};
+
+5. Build a bridge
+
+* $ cd contiki-2.4/tools/sky/uip-bridge
+* $ make connect
+* $ shift+ctrl+t        (opens a new terminal tap)
+* $ make bridge
+
+Now the bridge node and the Linux should be a router for your IPv6 enabled sensor nodes. Make sure you have some nodes (JCreate, Tmote Sky, Raven LCD, etc) with some IPv6 software and then try to ping some of your nodes with ping6 and see what happens! Notice that you have to add %tap0 after the IPv6 address, in order to use the right interface, e.g.:
+
+* $ ping6 fe80::0212:7400:10cf:a5c9%tap0
+
+Note: if you run "tcpdump -i tap0" you will see the IP addresses of your nodes when they ask for routers (Router Solicitation).
+
+6. Enable WLAN
+
+=== Setting up the IPv6 GOGO6 Tunnel ===
+
+To setup the IPv6 tunnel, there are following steps needs to be performed:
+
+1. Create an account on the [http://gogonet.gogo6.com] to access the Greenet6 website. follow the link: [http://gogonet.gogo6.com/page/freenet6-tunnelbrokerdownloadthegogoCLIENT]
+
+* To get a static IPv6 address or get a /56 network you need to get an account on the Freenet6 server. Create your account at this page:
+[http://gogonet.gogo6.com/page/freenet6-registration]. Remember that this username and password can be used in go6.conf file, when we setting the ipv6 tunnel.
+
+* Download the gogoCLIENT for your System, In our case we have Ubuntu so download the Client 6.0 Source Code (Linux/Unix/MacOS/BSD). http://gogonet.gogo6.com/page/download-1
+* Follow the HEX_DC_0005_Gateway6_Client_Guide (PDF) (page-61) contained in the gw6c package for the installation on your ubuntu machine. But for simplicity the steps are as follow.
+
+2. Complete the following steps to install the gogoCLIENT from the source code: 
+
+a. Retrieve the source code (*.tgz or *.zip) and decompress it to a temporary directory. 
+
+/temp$ tar –xf  gw6c-6_0-RELEASE-src.tar
 
 
+b. Compile the gogoCLIENT.
+
+/temp/gw6c-6_0_1$ make all
+
+c. To install the gogoCLIENT in the /usr/local/gw6c directory with the necessary files, run the following command: 
+
+/gw6c-6_0_1$ make installdir=/usr/local/gw6c install
+
+d. Executing the gogoCLIENT requires the files listed below: 
+
+The gw6c binary file (gw6c) located in the bin directory 
+A sample gw6c.conf file 
+The template subdirectory containing the operating system scripts
+
+e. In order to run the IPv6 tunnel as DNS, setup gw6c.conf file; the setting for the usr/local/gw6c/bin/gw6c.conf
+
+Suppose we create an account with username.
+  
+username: sensei-oulu
+password: *******
+
+$ sudo nano gw6c.conf
+
+Change the following configurations:
+userid=sensei-oulu
+passwd=*******
+server=authenticated.freenet6.net
+auth_method=any
+Other configurations: leave as default
+
+Whole gw6c.conf file is at the end of this document.
