SDWAN Update Static Route not Running

[tobezero]

Dear Forums,

we have problem in SDWAN only in HO site, even tough we set same config in HO and DC.

that update static route enabled not running. even in in performance SLA with ping to 8.8.8.8, already have monitoring that ALL ISP interface UP, and ALL MPLS interface down.

the problem is all interface have route to 0.0.0.0/0.0.0.0 (ISP and MPLS), BUT only happen inside CLI fortigate HO this happen.

ONLY In fortigate HO,

Fortigate SLI check with ping 8.8.8.8 cannot resolved hostname, do the traceroute 8.8.8.8 the route is to other site (DC)

but for all subnet LAN in HO, from PC can ping 8.8.8.8 and traceroute 8.8.8.8 get outside with WAN, and can have failover to other ISP WAN port.

and from all HO Subnet can ping to all DC Subnet.

check in fortigate DC, (everything fine)

Fortigate SLI check with ping 8.8.8.8 OK status, do the traceroute 8.8.8.8 route is to WAN port

and for all subnet LAN in DC, from PC can ping 8.8.8.8 and traceroute 8.8.8.8 get outside with WAN, and can have failover to other ISP WAN port.

and from all DC Subnet can ping to all HO Subnet.
