This section describes how to configure WAN redundancy. It includes the following topics:

You can configure multiple interfaces to provide a degree of redundancy across the WAN between the Core and the Edge. This redundancy ensures that any failure along the WAN path can be tolerated by the Core and the Edge, and is called WAN redundancy.

WAN redundancy provides multiple paths for connection in case the main Core to Edge link fails.

To configure WAN redundancy, you perform a series of steps on both the data center and branch side.

You can use both the in-path interfaces (inpathX_Y) or Ethernet interfaces (ethX_Y) for redundant WAN link configuration. In the examples below the term intf is used to imply either in-path or Ethernet network interfaces.
