In the given ADVPN (Auto-Discovery VPN) topology, BGP is being used to dynamically establish routes between spokes. The neighbor-range configuration is crucial for simplifying BGP peer setup by automatically assigning neighbors based on their IP range.

set neighbor-group advpn

● Theneighbor-groupparameter is used to apply pre-defined settings (such as AS number) to dynamically discovered BGP neighbors.

● Theadvpnneighbor-group is already defined in the configuration, and assigning it to the neighbor-range ensures consistent BGP settings for all spoke neighbors.

set prefix 172.16.1.0 255.255.255.0

● This command allowsdynamic BGP peer discoveryby defining a range of potential neighbor IPs (172.16.1.1 - 172.16.1.255).

● Sinceeach spoke has a unique /32 IPwithin this subnet, this ensures that any spoke within the172.16.1.0/24range can automatically establish a BGP session with the hub.

The exhibit shows anactive-passive HA (high availability) clusterwith two virtual clusters, where FortiGate_A is the primary device for both Core1 and Core2. If the goal is to haveFortiGate_B take over Core2 traffic, itspriority must be higherthan FortiGate_A forVirtual Cluster 2.

Currently, FortiGate_A has a priority of150for Core2, while FortiGate_B has128. IncreasingFortiGate_B’s priority to 200ensures it becomes theprimary for Virtual Cluster 2, taking over the Core2 VDOM traffic while keeping Core1 traffic on FortiGate_A.

Disabling override would prevent forced failovers but wouldn’t change the role distribution. Adjusting the load-balancing method is irrelevant in anactive-passive setup, as it only applies to active-active configurations.

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.
