To implement ADVPN 2.0 in an already configured SD-WAN topology, the update must occur on the branches.

"When enabling ADVPN 2.0 features (such as enhanced shortcut capabilities), it is required to update the SD-WAN configuration on all branch FortiGates. This allows the branches to support and negotiate the new shortcut and performance optimization features, while the hub configuration typically does not require modification unless introducing entirely new capabilities."

This approach ensures backward compatibility and staged rollout of advanced ADVPN features.
