Which EIGRP packet type is sent as a multicast when a new route is discovered, and sent as a unicast to synchronize topology tables when neighbors initialize?

• 300-410 : All Parts

Explanation:
EIGRP update packets are sent as a multicast when a new route is discovered, and sent as a unicast to synchronize topology tables when a neighboring router initializes.Whenever EIGRP only needs to communicate with a single neighbor, it sends a unicast to that neighbor instead of the standard multicast. In this case, it unicasts a packet to update a new EIGRP router on the network with the information that all other routers on that network already know.Hellos for neighbor discovery and maintenance are always multicasts.ACKs are hellos without data, and are always unicast.Queries are always multicast.Replies to queries are always unicast.
