WAN-to-WAN forwarding

Enabling WAN-to-WAN forwarding on the MCN, allows the MCN to advertise remote site routes.

  • Clients are aware of MCN local routes and other client site routes.
  • From client perspective, all routes are considered as MCN routes.

When WAN-to-WAN forwarding is not enabled on the MCN, Branch to Branch communication issues are encountered in the customer network.

Appliances running in client mode are unaware of other branches subnets until WAN-to-WAN forwarding is enabled on the MCN. Enabling this option makes the branch SD-WAN nodes aware of other branch subnets. The traffic destined to other branches is forwarded to MCN. MCN routes it to the correct destination.
