v8 v9 258 258 Congratulations! You are now running a non-IP core network on your four routers, along with a (primitive) non-IP multipath routing algorithm. You're ready to experiment with this configuration. 259 259 260 == 6. Send some traffic ==260 == 2b. Send some traffic == 261 261 262 262 Now you'll use your two edge hosts, '''hostA''' and '''hostB''' to send traffic along your network. Since these end hosts are not running your modified protocol, they'll rely on the '''top''' and '''bottom''' routers to transform their IP packets into your modified protocol on entry to the core network and back into IP packets on exit. … … 274 274 That's it! Now, let's look inside to see what's going on. 275 275 276 == 7. Looking under the hood ==276 == 2c. Looking under the hood == 277 277 278 278 Please note: the interface names and MAC addresses below are for the sample configuration shown in the figure above. You will want to refer to your network diagram to get the correct interfaces and addresses for your configuration. … … 280 280 Let's take a look at what's happening in the four routers in your configuration. There are two basic router configurations. (You can find all of these files on any of your router hosts.) 281 281 282 === 7b.Packet transformation ===282 === Packet transformation === 283 283 284 284 i. The more interesting configuration appears here, in the '''top.click''' configuration file. In a local terminal type: … … 330 330 The configuration for the '''bottom''' router is exactly symmetric, routing packets between '''hostB''' and the core network, but using different graffiti. 331 331 332 === 7b.Simple Forwarding ===332 === Simple Forwarding === 333 333 334 334 The '''left''' router configuration is much simpler. In a local terminal type: … … 357 357 This configuration just blindly forwards packets. It picks up any packet from the '''top''' router, updates the Ethernet header, and passes it along to the '''bottom''' router. The same applies in the reverse direction. Again, the configuration for the '''right''' router is exactly analogous. 358 358 359 === 7c.Monitoring your core network ===359 === Monitoring your core network === 360 360 361 361 Let's watch how the packets travel through the network.
