1. Introduction

RipEX provides Backup routes functionality to increase reachability in networks through redundant paths.

See the following example, where we have three possible paths between RipEX A and RipEX B. The direct radio link is set as the primary path (because it is direct). The path over RipEX C is the first backup option (two hops) and if this path also fails, GPRS backup path is ready in case of radio failure. In cellular networks, data transfer is charged and so it is used as the last option here.

Path priorities can be changed according to our requirements. The path with the highest priority is always the primary one (the direct radio link in our example) and the path with the lowest priority is the last option (GPRS in our example).

Thanks to the Backup routes functionality, RipEX can handle various network problems without interrupting the desired network communication.

The Backup routes functionality can be used in the Router mode only.

The Backup routes functionality is supported by the SNMP, see SNMP Application Note for further details.
