In OSPF, what is the function of the "Hello" packet?

• It is used for error reporting.

• It checks neighbor reachability.

• It contains the full routing table update.

• It sends topology changes.

Which multicast address does OSPF use to send Hello packets?

• 224.0.0.5

• 224.0.0.6

• 239.1.1.1

• 225.2.2.2

What is an advantage of using OSPF?

• It does not require authentication.

• It uses a single algorithm for both IPv4 and IPv6.

• It supports fast convergence.

• It is easier to configure than RIP.

What command enables OSPF on a router?

What command is used to verify OSPF neighbors?

• show ip ospf interface

What is the primary purpose of an ACL?

• Encrypt traffic

• Filter network traffic

• Speed up routing decisions
