Redundant OSPF routing over IPsec

This example sets up redundant secure communication between two remote networks using an Open Shortest Path First (OSPF) VPN connection. In this example, the HQ FortiGate unit will be called FortiGate 1 and the Branch FortiGate unit will be called FortiGate 2.

The steps include:

1. Creating redundant IPsec tunnels on FortiGate 1.
2. Configuring IP addresses and OSPF on FortiGate 1.
3. Configuring firewall addresses on FortiGate 1.
4. Configuring security policies on FortiGate 1.
5. Creating redundant IPsec tunnels for FortiGate 2.
6. Configuring IP addresses and OSPF on FortiGate 2.
7. Configuring firewall addresses on FortiGate 2.
8. Configuring security policies on FortiGate 2.
