RUTX09 Failover

Summary

This chapter is an overview of the Failover and Load Balancing functions in RUTX11 routers.

Failover

---

This function allows you to back up your primary connection in case it goes down. For example, when the primary connection fails, the router tries to use the backup with lover priority and if this one is unavailable or fails too, then the router tries the backup with even lower priority.

In order to set priorities, simply press left mouse click, then drag the interface to the 1st, 2nd or other position and then press Save & Apply.

Below is an example of Failover settings section.File:Networking rutx11 manual failover v1.pngBy pressing Edit button, you can find more Failover interface settings. More information and example are presented below.File:Networking rutx11 manual failover confing v1.png

field name	value	description
Enable	off | on; Default: off	Toggles the interface ON or OFF
Interval	Default: 3	Number of seconds between each test
Method	Default: Ping	Method, how internet connection will be tested
Track IP	IP;Default: 8.8.4.4; 8.8.8.8	The hosts to test if interface is still alive. If this value is missing the interface is always considered up
Reliability	Default: 1	Number of hosts that must reply for the test to be considered as successful. Ensure there are at least this many hosts defined or the interface will always be considered down
Count	Default: 1	Number of pings to send to each host with each test
Up	Default: 3	Number of successful tests to considered link as alive
Down	Default: 3	Number of failed tests to considered link as dead

Load Balancing

---

Load balancing lets users create rules that divide traffic between different interfaces. Below is an example of Load Balancing settings window.File:Networking rutx11 manual load balancing v1.pngAs you may notice from the image above, the configuration is very simple. You can assign ratio values to WAN interfaces. The ratio values represent a percentage of load that will go through an interface. For example, if you set that 3 parts of traffic would go through the Mobile interface and 2 parts would go through the Wired interface, it would mean that roughly 60% (3/5) of data will be transferred through Mobile, 40% (2/5) through Wired. If the ratios would be different, say Mobile: 5, Wired: 10, then 33% (5/15) of data would be transferred through Mobile, and 66% (10/15) would go through Wired.

If you press Edit button, you will be transferred to the same interface settings that were described in Failover section.
