Hello Guys,

More interesting to a laboratory level of CCNP. This laboratory is quite simple, but illustrates the way a problem we all Network Engineers will have to face in the future.

As the wheel IPv4 Internet will be a great challenge migrate it to use IPv6 in all its points. This laboratory is illustrated the GRE tunneling between two locations using the Internet as a means (R2 simulating an IPv4 network).

Below is the topology of the network.

The IOS is used advipservicesk9-c7200-mz.124-9.T.bin available in HD blog. Follow the same recommendations for the laboratory: use and abuse of show commands and debug, modify and use the laboratory to study and learn .

Below is presented a link to download.

Lab IPv6 - 6-to-4 Tunneling (updated)

Hello Guys,

The topic is covered in BSCI routing and is expanded including a new version of IP protocol, the IPv6. This new protocol will provide many more tens of IPs compared to IPv4 is used today.

The IPv6 for many (including me) is very obscure and complicated, but if you study with attention and practice quite calm through laboratories you understand its operation, including giants such addresses.

The laboratory that I am offering I did to practice addressing, summarization and working with the OSPFv3 (OSPF for IPv6).

I setup a Multi-area as can be seen in the picture attached and made a summarization of some subnets to see your reflection in the routing table and OSPF in the LSAS. Remember, the OSPFv3 differs slightly from its predecessor on the LSAS, so stay tuned.

As the oldest IOSs not support the OSPFv3 was necessary to use the IOS 12.4 (T) 9, the router 7200. The image is available on this link in the folder IOS - Dynamips.

Emphasize that the configuration in NVRAM of the router is complete, and after setting everything TXTs that are in the file is the initial configuration.

Below the laboratory:
