Question

WAN backup using SD-WAN

Hello,

 

I need to setup a second WAN link strictly as backup of WAN1, using SD-WAN. Is it possible to do that? e.g. passing traffic strictly from WAN1 and if and only if WAN1 fails, then pass traffic through WAN2. From what I have seen, SD-WAN is not capable for this configuration, but do you know if there is any configuration trick to do this?

 

Thanks

    If that's what your intending use of two WAN interfaces, I wouldn't bind them in an SD-WAN interface. Instead, just set up a fail-over between two individual interfaces.

    Agreed.  The entire purpose of SD-WAN is to make the two interfaces appear as one to make it smoother and easier to do things like balancing/sharing/etc. No reason to set it up if you're not going to use the functionality it provides.
