Dynamic route on Fortigate SDWAN

Hi, In existing network already had a OSPF routing protocol

Is it possible on Fortigate SDWAN if I do not add a "static route 0.0.0.0 0.0.0.0 virtual-wan-link", Is it mendatory?

I don't believe you can have OSPF learn the SD-WAN default route. Pretty sure it needs to be input as a static route. Is there a reason you do not want to do it?

My customer has 2 sites, and these are connecting with OSPF routing (with 2 MPLS layer2 links)

And we want feature of Fortigate SDWAN to load balancing these 2 links

 

But there are many routes, we decided to keep dynamic routing

Perfect. Yes, so you need to add the manual static default route pointing to your SD-WAN virtual link (zone). The member interfaces inside the zone will still maintain all of their respective dynamic routes (including defaults, if any). These routes will and can be used in the SD-WAN link selection criteria on top of your SD-WAN rules and SLA matching (i.e. FGT will look to see which interface has best route to destination still).
