==Router configuration==
Most of the router's configuration will done via a command line interface by executing SSH commands. For examples provided in this guide, we will be using the Linux '''Terminal''' application. This is not the only available method. You can find detailed instruction on all command line interface available in RUTxxx routers '''[[Command line interfaces|here]]'''. Choose one that is available or most preferred by you and you will still be able to follow the guide step-by-step regardless of which method you chose as the commands used will remain identical.

* If the connection was successful, we can start the traffic split configuration. First, we'll need to add an additional routing table. This can done by issuing the following command:
* If the connection was successful, we can start the traffic split configuration. First, we'll need to add an additional routing table. This can be done by issuing the following command:
echo "<span style="color:red>5 rt</span>" >> <span style="color:red>/etc/iproute2/rt_tables</span>
echo "<span style="color:red>5 rt</span>" >> <span style="color:red>/etc/iproute2/rt_tables</span>
This adds a new routing table called ''rt''. ''/etc/iproute2/rt_tables'' is a file used by the ''iproute2'' utilities which translate user friendly names given on the command line into integer values used by the kernel. So the number ''5'' is just the way for the ''iproute'' to identify the table.
