To figure out which interfaces to bring down, you can inspect the properties of a link in Flack and see which IP corresponds oneach link and find the interface with this IP address.319 The two interfaces that are connected to `source` and `PC-WashDC` are `mv1.1` and `mv1.2` respectively. To figure out which interfaces to bring down, you can inspect the properties of a link in Flack and see which IP corresponds to each link and find the interface with this IP address. 320 320 321 321 [[Image(linkdetails.png)]] … … 330 330 Bring down IP alson on the `source` on the interface that connects to `R2`. 331 331 == 4b. Run Layer 2 Ping == 332 From source try to ping `R2`. First we will need to figure out the MAC address of `R2`. We can find the MAC address the same way as we found the interface names in the previous step. The <INTERFACE_NAME> is the interface on `source` that corresponds to the link with `R2`; it is the interface we removed the IP from on the previous step. 332 From source try to ping `R2`. To perform a Layer 2 ping we are going to use a program that is installed on all the nodes (pingPlus) that can be downloaded [http://www.gpolab.bbn.com/local-sw/ here]. 333 The command is : 334 {{{ 335 sudo /local/tutorial/pingPlus/pingPlus <MAC_ADDRESS> <INTERFACE_NAME> 12345 336 }}} 337 338 * <MAC_ADDRESS> is the mac address of the destination host. You can figure out the mac address of `R2` the same way as we found the interface names in the previous step. 339 * <INTERFACE_NAME> is the interface on `source` that corresponds to the link with `R2`; it is the interface we removed the IP from on the previous step. 333 340 334 341 Run : 335 {{{336 sudo /local/tutorial/pingPlus/pingPlus <MAC_ADDRESS> <INTERFACE_NAME> 12345337 }}}338 342 339 343 The result should look like : … … 402 406 = 6.
