Multi-WAN Load Balance Weight 0 - What does this mean?

Router
1

Multi-WAN Load Balance has weight options from 0 to 10.
Does 0 mean do not use that member? What if that is the only member that is active?

I have 3 WAN sources - WAN1 (Fiber), WAN 2 (5G) and WAN3 (USB LTE).
WAN1 is set at weight 2, WAN2 is set at weight 4 and WAN3 is set at weight 0.

If WAN1 and WAN2 both go down, I would like WAN3 (USB LTE) to be used. Otherwise I don’t want WAN3 to be used.
In my testing, when I unplugged WAN1 and WAN2, I noticed the router was indeed using WAN3 (USB LTE) even when the weight was 0. Is this how its supposed to function with weight 0?

Hi,

Yes, in Load Balance mode, if the Load Ratio of an interface is set to 0, that interface will not be included in the load balancing group, meaning traffic will not be routed through this interface.

However, if other interfaces become unavailable, there is still a fallback default route that may route traffic through this interface.

default proto static
        nexthop via 192.168.6.1 dev eth1 weight 1
        nexthop via 192.168.8.1 dev eth0.2 weight 1
default via 192.168.6.1 dev eth1 proto static src 192.168.6.219 metric 1
default via 192.168.8.1 dev eth0.2 proto static src 192.168.8.220 metric 2
default via 10.49.34.220 dev usb0 proto static src 10.49.34.234 metric 3

Ok, that is awesome!
It would be great to also explicitly add an interface as ‘backup’ when non-zero/default members fail in GL-iNet GUI.

Thank you for your suggestion.
We’ll discuss this internally to see if we should add an explanation to the relevant documentation/GUI.
