Multi-WAN vs SD-WAN, a little confused....
I am in the process of migrating from an XTM515 to an M270. I have brought my configuration over from the XTM device, and when I first tried to save it to the M270, I did get flagged that the PBR no longer works in this version (M270 came with V12.4.1 installed), so I modified all the policies using PBR to remove that option.
I did only have a set number of outbound policies using PBR, as the backup circuits are much smaller than our primary fiber circuit and we were limiting what would go out in the event our primary circuit went down.
I have read that to accomplish the same type of action I now need to setup an SD-WAN action, and apply that to the policies I had been using the PBR in the XTM setup, I think I understand that enough to setup (maybe lol)
I think I am just a little confused, because when I look at the Multi-WAN section, it shows failover configured for my 3 external interfaces.
So my question is:
How does Multi-WAN failover vs SD-WAN setup really work?
On my XTM, I also had multi-wan failover setup,
If I have a policy that is not configured to use the SD-WAN routing, am I correct in believing that the outbound traffic on other policies will not go out? That was how I believed the PBR had worked in the past.
Thanks for any help clearing up my confusion, my brain is a bit overwhelmed in trying to read up on all the changes from my lowly 12.1.3 XTM up to the more current updates I will now be able to use.
Thanks again for all the read through (hope I made sense), and helping me understand
