 To simplify the configuration process, we assume the `interface-cost` and the `hello-interval` are both set to 10 seconds for every virtual interface. The main information needed from each node is the virtual interface's `address` and its `prefix-length`, as well as the router's `router-id` that is required for the `protocol` section in the configuration file.

 Verify the `XORP` process is running

-Then Start `XORP` for `router-2`, `router-3` and `router-4` in the same way.

-If you need to stop `XORP` for some reason, there is no one-key method to stop `XORP` process, so we have to kill every `XORP`-related process. We can use the command like the one below to kill all `XORP` process at one time.
+lnevers@router-1:/usr/local/xorp/sbin$ ps -ef | grep xorp

+Now you have routing running on all four router!
