Summary
In this example we will setup redundant links using dynamic routing where 2 routers will be connected using multiple links directly – Main WAN and two Backup WANs in order to make sure LAN devices on each end would be available in case Main links fail.
Configuration overview & prerequisites
For this example, we will need two routers with 3 separate WAN interfaces. It can either be Wired links or Private Mobile networks. In this example we will use 3 wired links for the simplicity of testing. However, there can be other variations, such as 1 Wired link and 2 Mobile links. Each WAN on both ends has to be in the same private network. In other words:
- RUT1 WAN1 interface must be able to reach RUT2 WAN1 interface;
- RUT1 WAN2 interface must be able to reach RUT2 WAN2 interface;
- RUT1 WAN3 interface must be able to reach RUT2 WAN3 interface.
