Rules and routing

In what sequence does FortiGate evaluate the following elements during route lookup?

  • A SD-WAN rules, ISDB routes, policy routes, BGP routes
  • B SD-WAN rules, policy routes, static routes, ISDB routes
  • C Policy routes, ISDB routes, SD-WAN rules, static routes
  • D Policy routes, SD-WAN rules, Internet Service Database (ISDB) routes, BGP routes
