Neighbor relations for both sides only interactive HELLO message, not interactive link-state database (LSDB), and the adjacency relations will interact all the information (LSA), neighbors and the distinction between adjacent mainly: (radio) used in Ethernet networks, to elect a center node, called DR, namely all the Ethernet device to interact with the DR all information, and to the interaction between the HELLO message, database synchronization by DR radio link state database regularly, do so mainly: the purpose of reducing the Ethernet need interaction in the number of link-state database

After a neighbor relationship, is two - way synchronous exchange after the LSDB is FULL,
