How can you ensure the corporate FortiGate learns the 192.

In enterprise hub-and-spoke environments, the most scalable and efficient way to ensure the corporate Hub learns the internal networks of remote branches (such as 192.168.1.0/24) is through the use of dynamic routing protocols. Implementing OSPF over IPsec allows the Hub and Spoke units to exchange routing information automatically through the VPN tunnel. Once the OSPF adjacency is established over the IPsec interface, the spoke will advertise its local 192.168.1.0/24 network to the Hub, which then installs the route into its routing table. This avoids the administrative burden and potential errors associated with manually adding static routes for every remote site.
