CCNP ROUTE: LAB Setup for IPv6

The above diagram will be used for studying all IPv6 concepts in the CCNP ROUTE 642-902 curriculum.
This topology simulates three companies which connect to each other via the Internet.

Graphical Network Simulator (GNS3 0.8.3) has been used to build this topology. All routers are Cisco 2691 series, running the c2691-adventerprisek9-mz.124-25c image.
You can download this entire GNS3 CCNP lab (including the topology and configuration files for all routers) from HERE.

All 7 routers in the topology are initially configured with IPv4 addresses. All IPv6 settings will be added during the upcoming labs, depending on the scenarios.
All lab exercises will be based on these configurations, with a general reloading process after each excercise, so the settings made in one lab will not interact with those made in the next one. After each router reloading, all IP address settings will be automatically restored from the configuration files saved in the CCNP_ROUTE_IPv6 folder.

Note 1: Loopback interfaces (if any configured) are by default advertised with a /32 mask. You can advertise them as usual networks by configuring each interface as a point-to-point link.

Note 2: Routers R1, R2, R3 are considered belonging to the Service Providers offering the Internet/WAN services. Routers R4, R5, R6 are considered to be company edge routers.

Note 3: Do not forget to recalculate the IdlePC value for the routers once you start this lab in GNS3!

Note 4: Do not forget to edit the topology file (using a text editor) and modify the IOS path or other parameters according to your operating system and file locations!

Note 5: This topology and its related configuration can be improved in many ways, but since it is 100% functional and all the theoretical concepts are applied within the exercises with the expected results, it may be considered a good practice for the CCNP ROUTE exam.

Note 6: For any GNS3 errors when opening/using the topology please refer to http://forum.gns3.net/.

Note 7: If you see the below error when loading the GNS3 topology, check the project's "config" folder to see if the router config files have the .cfg extension, and not .cfg.txt or any other extension.
Local configuration configs\Rx.cfg cannot be found for router Rx, use default base config instead.

Most of the theory in the following labs comes from CCNP ROUTE 642-902 Official Certification Guide, Wendell Odom, Cisco Press, which is a great source of information for the ROUTE exam.

The initial configurations of the routers (these configs will be maintained after each reload):
