| 223 | Congrats you were able to run a multihop IP experiment. |
| 224 | |
213 | | == 3a. Login to VM@Utah == |
| 226 | GENI provides the capability of creating diverse, layer two topologies. The topology you have created includes connection at Layer 2. |
| 227 | The layer two part of your topology looks like this; the actual info of your topology might be different. |
| 228 | |
| 229 | In this exercise we are going to send layer 2 traffic between the hosts of our topology. |
| 230 | |
| 231 | == 3a. Bring Down IP at PCUT == |
| 232 | First of all lets bring down the IP configuration from our hosts. At the terminal of PCUT first run ifconfig to figure out which are the dataplane interfaces. Run : |
| 233 | {{{ |
| 234 | /sbin/ifconfig |
| 235 | }}} |
| 236 | |
| 237 | The output should look like : |
