Solution Design

The tenant administrator has completed SD-WAN network configurations. There are reachable routes between CPEs at the active and standby hub sites and the Internet on the LAN side.

  1. Access the Internet in centralized access mode.
  2. In centralized access mode, traffic from branch sites to the Internet is forwarded to the hub sites through the overlay network. After CPEs at the hub sites receive the traffic, the CPEs forward the traffic to the Internet on the LAN side and forward the traffic from the Internet to branch sites through the overlay network.
