<b>Explanation</b>
<b>Explanation</b>
The routers and the PC are connected to the same network (<i>192.168.1.0/24</i> via a switch. The purpose of the system is to provide an Internet connection for the PC via the the MASTER ({{#ifeq:{{{series}}}|RUTX|RUTX1|RUT_1}}) router and backup that connection via the BACKUP ({{#ifeq:{{{series}}}|RUTX|RUTX2|RUT_2}}) router in case the MASTER fails.
Below is alternate topology that does not contain a switch. The configuration is identical for both cases. However, while the topology above provides a connection backup in case of any type of failure, the topology below will only backup the connection if the MASTER router loses its connection but remains available inside the network (i.e., it will not backup the connection if the MASTER is, for example, powered off).

This section provides the configuration parameters used for the MASTER and BACKUP routers. The table below is contains a summary of the settings used. As you can see the configurations are identical with the exception of the <i>Priority</i> parameter.

===PC===

Now you will need to set up a static IP address configuration on your PC. For this example we will be using the following parameters:
IPv4 address: 192.168.1.3
Netmask: 255.255.255.0
Gateway: 192.168.1.253
If you are unsure of how to set up a static IP, please refer to one of our guides:
<ul>
<li>[[Setting_up_a_Static_IP_address_on_a_Windows_10_PC|Static IP for Windows]]</li>
<li>[[Setting_up_a_Static_IP_address_on_a_Ubuntu_16.04_PC|Static IP for Linux]]</li>
</ul>
==Testing and troubleshooting==
To test whether the configuration works, terminate the MASTER router's Internet connection (e.g., unplug the cable, remove the SIM card). If everything is okay, the PC should regain its connection to the Internet shortly after that.
Restore the Internet connection to the MASTER router .
