The multicast address FF02::5 is associated with which routers?

• A. All RIP routers
• B. All OSPF routers
• C. All EIGRP routers
• D. All switches

Answer: (B)

The multicast address FF02::5 is specifically designated for all OSPF (Open Shortest Path First) routers within an IPv6 network. When OSPF routers need to communicate routing information among themselves, they utilize this multicast address to ensure that all OSPF devices listen for their routing updates. In an OSPF configuration, routers join this multicast group so they can receive OSPF routing updates sent to this address. The "FF02::" prefix indicates that this is a link-local scope multicast address, meaning that the packets are intended for devices on the same local network segment. By using this designated multicast address, OSPF ensures efficient communication among all routers participating in an OSPF domain, reducing unnecessary traffic and allowing only the relevant routers to process the OSPF updates.
