H12-211 Exam - Question 91


Refer to the graphic. An administrator has configured OSPF on the two routers, following which he then implements the command silent-interface s0/0/1 on RTA.

What effect will this command have on the network? (Multiple Choice)

Show Answer
Correct Answer: B

The command silent-interface in OSPF disables a specified interface from sending and receiving OSPF Hello packets. Since OSPF relies on Hello packets to form and maintain neighbor relationships, using the silent-interface command on the s0/0/1 interface on RTA will prevent it from establishing or maintaining an OSPF neighbor relationship with RTB via that interface. Consequently, the OSPF neighbor relationship between RTA and RTB will fail.

Silent interface cannot send its information with other interfaces but it can save information coming from other interfaces

I am agree with Daniyal. OSPF doesn't delete de lsdb, so it mantain de lsdb in its memory. In my opinion, the correct answer it's A and B.

Doesn't LSDB get updated after the adjacency's been formed? And if interface is silent, it doesn't respond to Hello packets == no adjacency will be formed?

i think answer D is correct too, before the dead timer is exceeded they would be still neighbor but the RTA will not send updates.

B is correct : The silent-interface command disables an interface from receiving and sending OSPF packets.
