Specify the link cost in one of the following ways:
If you want to specify the cost of a link that was established from a CPE device, go to the SD-WAN → CPE section, click the CPE device, select the Tunnels tab, and click Management → Set cost next to the link.
If you want to specify the cost of one of the links in the table of all links, go to the Infrastructure section, click Management → Configuration menu next to the controller, go to the Tunnels section, and click Management → Set cost next to the link.
If you want to specify the cost of one of the links in the graphic topology with all links, go to the Infrastructure section, click Management → Configuration menu next to the controller, go to the Topology section, click the link, and click Set cost.
This opens a window; in that window, select the Override check box to specify the cost of the link. This check box is cleared by default.
In the Tunnel cost field, enter the cost of the link. If you want to specify the same cost for the opposite-direction link, select the Save for both tunnels check box. This check box is cleared by default.
Click Save.
The link cost is specified.
If you have specified the link cost for a link established from the CPE device, click Save in the upper part of the settings area to save the CPE device settings.
