Fortinet FCSS_EFW_AD-7.4 Exam With Confidence Using Practice Dumps

The output of the get router info ospf status command provides key information about the OSPF (Open Shortest Path First) configuration on the FortiGate device.

The FortiGate device is connected to multiple areas

● The output states: "This router is an ABR"

●ABR (Area Border Router)means the device is connected tomultiple OSPF areasand maintains routing information between them.

● This confirms that the FortiGate isnot just in one area, but at leastone backbone area (Area 0) and another OSPF area.

The FortiGate device injects external routing information

● The output states: "Supports opaque LSA"

●Opaque LSAs(Type 9, 10, and 11) are used inOSPF extensions, including those that support external route injection.

● Typically, ABRs or ASBRs (Autonomous System Boundary Routers)inject external routes, allowing routes fromother routing protocols (such as BGP or static routes) to be advertised into OSPF.

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.

neighbor-group:

● This command is used to group multipleBGP neighborswith the same configuration, reducing redundant configuration.

● Instead of defining individual BGP settings for each spoke, the administrator can create aneighbor-groupand apply the same policies, reducing manual work.

neighbor-range:

● This command allows the configuration ofa range of neighbor IPs dynamically, reducing the need to manually define each spoke neighbor.

● It automatically addsBGP neighborsthat match a given prefix, simplifying deployment.
