Fortinet NSE7_NST-7.2 Exam With Confidence Using Practice Dumps

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.

Understanding OSPF Roles:

In OSPF (Open Shortest Path First), routers can have different roles: Designated Router (DR), Backup Designated Router (BDR), and DROther. These roles help manage and optimize the OSPF network traffic.

DR and BDR are elected to minimize the number of adjacencies and reduce the amount of routing information exchange.

DROther routers are neither DR nor BDR but can still participate in the OSPF network by maintaining adjacencies with DR and BDR.

Analyzing the Exhibit:

The exhibit shows the OSPF neighbor states for the local FortiGate.

Neighbor ID 0.0.0.1 is in the state Full/DR (Designated Router).

Neighbor ID 0.0.0.3 is in the state Full/DROther (DROther).

Neighbor ID 0.0.0.10 has no specific designation, implying it is neither DR nor BDR.

Conclusion:

Since the local FortiGate shows neighbors in Full/DR and Full/DROther states and itself does not have a state of DROther, it can be concluded that the local FortiGate is not a DROther.

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.
