The title actually was a request that I encounter during my CCIE RS preparation. Of course, that in the real world, I would go straight forward and implement an access-list do drop selected packets. But since the lab environment is different for the real one, you might get a task like the above one.
Let’s assume that we have a network topology with a central router (R1) that connects 2 routers (R2 and R3), like in a hub and spoke diagram. Communication between R2 and R3 is done through R1. In this environment routing is already functional, implemented by dynamic or static routing (actually doesn’t matter this is not a topic for this presentation) and R2 can reach R3. We will drop all packets from R2 to R3, but telnet related packets (just to do things a little bit more interesting). As I specified before all this has to be achieved without access-list implementation.
Please have a look to this topology, to have a clear picture of the network environment. After you have checked the topology, watch the video presentation below:
Blaupunkt has a new car radio that can stream Internet stations over 3G, which allow users to tune in to any of about 16,000 stations from around the world.
The “New Jersey 600i” and “Hamburg 600i” radios, which are the first such in the world according to the company, are on show at this week’s Cebit trade fair in Hanover, Germany. By connecting over Bluetooth to a cell phone, the radios access a 3G Internet service and then stream almost any station that’s online. The radios work with the MiRoamer Internet database to grab information about available stations, and then your favorite programs are just a couple of button clicks away.
Beyond the price of the 3G data service it’s free to connect and listen to stations online.

Cisco and NASA this week said they are collaborating on an online global monitoring platform to capture, collect, analyze and report data on environmental conditions around the world.
Called “Planetary Skin,” the project will involve NASA and Cisco working to develop the online platform to capture and analyze data from satellite, airborne, sea- and land-based sensors across the globe. This data will be made available for the general public, governments and businesses to measure, report and verify environmental data to help detect and adapt to global climate change.
