Question #: 26
Topic #: 4

[All NSE7_EFW-7.2 Questions]

Refer to the exhibit, which contains a partial OSPF configuration.

What can you conclude from this output?

ANeighbors maintain communication with the restarting router.

BThe router sends grace LSAs before it restarts.

CFortiGate restarts if the topology changes.

DThe restarting router sends gratuitous ARP for 30 seconds.

Show Suggested Answer

Suggested Answer: B

From the partial OSPF (Open Shortest Path First) configuration output:

B) The router sends grace LSAs before it restarts: This is implied by the command 'set restart-mode graceful-restart'. When OSPF is configured with graceful restart, the router sends grace LSAs (Link State Advertisements) to inform its neighbors that it is restarting, allowing for a seamless transition without recalculating routes.

Fortinet documentation on OSPF configuration clearly states that enabling graceful restart mode allows the router to maintain its adjacencies and routes during a brief restart period.

Option C? FortiGate restarts if the topology changes? Sounds like a feature, not a bug! Who doesn't love a little surprise reboot now and then?

Hmm, I'm not sure. This OSPF configuration is giving me a headache. I need a cup of coffee before I can tackle this question.

I think Option D is correct. The restarting router sends gratuitous ARP for 30 seconds to let other routers know its new MAC address.

I agree, Option D is correct. The gratuitous ARP helps update the MAC address.

I agree with Mabelle, because grace LSAs help in maintaining network stability during router restarts.
