I just hat the following incident:
On a FGT 100E sd-wan is active and used for internet. There is SD-WAN SLA configured for each interface in sd-wan to check link health. Worked fine so far.
There used to be 4 interfaces in sd-wan and sd-wan SLA. One is deactivated in sd-wan always (should only be used by sd-wan when all others are down).
Now I added a new Interface to sdwan (and SD-WAN SLA) which still does not have an internet connection. I did this plenty of times with no problems. This time sd-wan behaved different.
Even though the Health Check marked the Link as down correctly, sd-wan started using it and it got sessions for no use.
On all other FGT we have SD-WAN does not do so. If a link is down it is not used.
Does anyone have a clue why it behaves so different here?
