OSPF Interface Network Types:

The network types of the interfaces on both FortiGate devices must match. Common network types include broadcast, point-to-point, and non-broadcast multi-access (NBMA).

Authentication Settings:

Both devices must have matching authentication settings (if authentication is used). This includes the same authentication type (none, simple password, or MD5) and the same password or key.

OSPF Router IDs:

Each OSPF router must have a unique router ID within the OSPF domain. The router ID is typically an IPv4 address selected from one of the router's interfaces or manually configured.

Link Costs and Interface Priority:

While link costs and interface priorities are important for route selection and designated router (DR) elections, they do not prevent OSPF adjacency formation if they differ.

BGP Advertisement: The output from the command get router info bgp neighbors 100.64.2.254 advertised-routes shows the routes that the local router is advertising to its BGP neighbor.

Output Analysis:

The Network column lists the networks being advertised.

The Next Hop column indicates the next-hop IP address for these routes.

The line *> 10.20.30.40/24 100.64.2.1 indicates that the 10.20.30.40/24 network is being advertised with a next-hop of 100.64.2.1.

Local Router's Role: Since the output lists the advertised routes, it means that the local router (with router ID 172.16.1.254) is advertising the 10.20.30.40/24 network to its neighbor 100.64.2.254.

This confirms that the local router is indeed advertising the specified network to its BGP neighbor.

Soft Reset of BGP:

Performing a soft reset of BGP is a common method to resolve issues where prefixes are not being received. It forces both BGP peers to resend their complete routing tables to each other.

This can be done using the command: execute router clear bgp soft in and execute router clear bgp soft out.

Network Import Check:

The network-import-check command controls whether the FortiGate should verify that the prefix exists in the routing table before advertising it.

Disabling this check can resolve issues where valid prefixes are not advertised due to stringent verification.

The command to disable this is: config router bgp set network-import-check disable end.

BGP Configuration Verification:

Ensure that the BGP configuration on FGT-B is correctly set to advertise the network 172.16.54.0/24.

Verify that the network statement is correctly configured and matches the intended prefix.

Current Configuration Analysis:

The firewall policy currently allows ICMP traffic from port1 to port3, enabling the ICMP echo request to reach the server.

However, for the server to send an ICMP echo reply back to the laptop, the traffic must be allowed from port3 to port1.

Required Configuration:

To ensure the server at 10.4.0.1/24 can send the ICMP echo reply back to the laptop at 10.1.0.1/24, the administrator needs to configure a new firewall policy.

The policy must explicitly allow ICMP traffic from port3 to port1.

Steps to Configure:

Access the FortiGate configuration interface.

Navigate to the Firewall Policy section.

Create a new policy allowing ICMP traffic from port3 to port1.

Save and apply the new policy to ensure bidirectional ICMP traffic is permitted.

Refused Connection: A refused connection typically indicates a mismatch in the TCP port configuration between the FortiGate and the collector agent. Ensuring both are configured to use the same TCP port is crucial for proper connectivity.

Mismatched Pre-Shared Password: If the pre-shared password configured on the FortiGate does not match the one set on the collector agent, authentication will fail, leading to connectivity issues.

Inability to Reach IP Address: This can occur due to network issues such as incorrect routing, firewall rules blocking traffic, or the collector agent being down. Verifying network connectivity and the status of the collector agent is necessary to resolve this issue.
