SD-WAN rules define specific routing options to route traffic to an SD-WAN member.

If no routing rules are defined, the default Implicit rule is used. It can be configured to use one of five different load balancing algorithms. See Implicit rule for more details and examples.

This example shows four methods to equally balance traffic between the two WAN connections. Go to Network > SD-WAN Rules and edit the sd-wan rule to select the method that is appropriate for your requirements.

  • Source IP (CLI command: source-ip-based):

    Select this option to balance traffic equally between the SD-WAN members according to a hash algorithm based on the source IP addresses.

  • Session (weight-based):

    Select this option to balance traffic equally between the SD-WAN members by the session numbers ratio among its members. Use weight 50 for each of the 2 members.

  • Source-Destination IP (source-dest-ip-based):

    Select this option to balance traffic equally between the SD-WAN members according to a hash algorithm based on the source and destination IP addresses.

  • Volume (measured-volume-based):

    Select this option to balance traffic equally between the SD-WAN members according to the bandwidth ratio among its members.
