Next-hop IP address:

For a static route to be added to the routing table, the next-hop IP address must be reachable. If it is not reachable, the route cannot be considered valid and will not be added.

Interface status:

If the interface specified in the static route configuration is down, the route will not be added to the routing table. The interface must be up and operational for the route to be valid.

Priority and Distance:

While priority and administrative distance affect route selection, they do not prevent a route from being added to the routing table. Instead, they influence which route is preferred when multiple routes to the same destination exist.

Routing Configuration and Troubleshooting Guides

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 inandexecute router clear bgp soft out.

Network Import Check:

Thenetwork-import-checkcommand 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.

RTT (Round Trip Time):

RTT in the context of the FortiGuard server list indicates the time it takes for a request to be sent to a FortiGuard server and for a response to be received.

This metric helps determine the latency between the FortiGate device and the FortiGuard servers, which is crucial for ensuring efficient and quick updates and responses for services like web filtering and antivirus updates.

Server Selection:

The FortiGate device uses RTT values to prioritize servers. Servers with lower RTT values are preferred as they respond faster, ensuring minimal delay in processing requests.

This improves the overall performance of FortiGuard services by reducing the time it takes to communicate with the servers.
