A network administrator uses a LAN analyzer to troubleshoot OSPF router exchange messages sent to all OSPF routers.
To which one of these MAC addresses are these messages sent?
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
OSPF (Open Shortest Path First) is a routing protocol that uses multicast IP addresses to exchange routing information between routers. OSPF routers use multicast addresses to send and receive OSPF packets, and these addresses map to specific MAC addresses.
The MAC addresses used by OSPF depend on the type of OSPF packet being sent. There are three types of OSPF packets:
The MAC address used for OSPF packets depends on the type of packet and the destination IP address. Here are the MAC addresses used by each type of OSPF packet:
Therefore, the answer to the question is B. 01-00-5E-00-00-05, which is the multicast MAC address used by OSPF for Hello and DBD packets.
