Create Outbound Multi-Link elements

Outbound Multi-Link elements group together NetLinks as a single entity and set options for load balancing.

Before you begin

Configure routing with at least two NetLinks.

To use the round trip time NetLink selection method for load balancing, you must configure the probing settings in the Static NetLink or Dynamic NetLink properties.

You can create multiple Outbound Multi-Link elements, and each NetLink can belong to more than one Outbound Multi-Link element at the same time.

To create the Outbound Multi-Link element, you must define the following:
  • Which NetLinks are included
  • The load-balancing method for determining which link is selected for each new outbound connection
  • Whether each NetLink in the Outbound Multi-Link element is an Active or Standby NetLink

The Outbound Multi-Link elements you create do not work on their own; you must use them in the Engine Policy’s NAT rules to select traffic for outbound load balancing.

Note: If you use element-based NAT, the default NAT address works like an Outbound Multi-Link element. You do not need to create an Outbound Multi-Link element when you use element-based NAT.

Steps

  1. Select Secure SD-WAN Configuration.
  2. Browse to Traffic Handlers.
  3. Right-click Traffic Handlers, then select New > Outbound Multi-Link.
  4. In the Name field, enter a unique name.
  5. From the Method drop-down list, select the method for link selection.

Next steps

Select NetLinks for the Outbound Multi-Link element.
