Help to configure redundancy
I would like to set up redundancy on my MPLS line. To do this, I need to configure my SonicWall.
I have a backup line and a main line. The main line is always up, and the backup line is down until the main line is down.
I tried to do the configuration with port redundancy, but unfortunately it doesn't work as we'd like, as the link to the switch is always up.
So I tried the other possibility with LAG but as it does round-robin then, there are packets that are lost.
What can I do to achieve what I want ? Or is there any other way to do what I want?.
Thank you in advance for your help.
