QuestionQ4

SD-WAN

Which two statements are true when traffic matches the implicit SD-WAN rule?

Choose two
  • A The sdwan_service_id flag in the session information is 0.
  • B All SD-WAN rules have the default setting enabled.
  • C Traffic does not match any of the entries in the policy route table.
  • D Traffic is load balanced using the algorithm set for the v4-ecmp-mode setting.
Explanation

The implicit SD-WAN rule is used only after traffic fails to match a user-defined policy-route entry and is forwarded through normal FIB routing. Its session record uses sdwan_service_id=0 in FortiOS versions that display this field. SD-WAN-enabled devices use the SD-WAN load-balance-mode setting rather than v4-ecmp-mode for this behavior.
