A: Hello is used to keep a neighbor and does not require each neighbor to replicate a single unicast packet. LSU is the link state with the new, a network segment generally has the DR and Bdr, both of which need to establish a neighbor with R-other and monitor the multicast address of the 224.0.0.6. If LSU sends it out from Drother, not sending it to the multicast address, sending it to unicast will result in a waste of bandwidth and a burden on the device.DD is sent when a neighboring relations
