When configuring aloopback interface as the BGP sourceforconnecting to an ISP, two important settings must be applied:

1.Enable EBGP Multihop (ebgp-enforce-multihop)

BGP normally expects directly connected neighbors, but since the ISP and FortiGate A are usingloopback interfaces,packets will not be sent directly between their physical interfaces.

Theebgp-enforce-multihopcommandallows BGP to form an eBGP peering over multiple hops.

2.Set the Update Source (update-source)

Since FortiGate is using aloopback interface as the source, theupdate-sourcecommand ensures thatBGP updates originate from the loopback interfacerather than a physical interface.

This is essential becauseBGP peers must match the source IP with the configured neighbor address.

Use metadata variables to dynamically assign values according to each FortiGate device:Metadata variables in FortiManager allow device-specific configurations to be dynamically assigned without manually configuring each FortiGate. This is especially useful when deploying multiple devices with similar base configurations.

Use provisioning templates and install configuration settings at the device layer:Provisioning templates in FortiManager provide a structured way to configure FortiGate devices. These templates can define interfaces, policies, and settings, ensuring that each device is correctly configured upon deployment.

Add FortiGate devices on FortiManager as model devices, and use ZTP or LTP to connect to FortiGate devices:Zero-Touch Provisioning (ZTP) and Local Touch Provisioning (LTP) help automate the deployment of FortiGate devices. By adding devices as model devices in FortiManager, configurations can be pushed automatically when devices connect for the first time, reducing manual effort.

TheInternet Service Database (ISDB)in FortiGate is used to enforce content filtering atLayer 3 (Network Layer) and Layer 4 (Transport Layer)of the OSI model by identifying applications based on theirpredefined IP addresses and ports.

FortiGate has a predefined list of all IPs and ports for specific applications downloaded from FortiGuard:

● FortiGate retrieves and updates apredefined listof IPs and ports for different internet services fromFortiGuard.

● This allows FortiGate to block specific services atLayer 3 and Layer 4without requiring deep packet inspection.

The ISDB blocks the IP addresses and ports of an application predefined by FortiGuard:

● ISDB works by matching traffic to knownIP addresses and portsof categorized services.

● When an application or service is blocked, FortiGate prevents communication bydenying traffic based on its destination IP and port number.
