Global	Synchronize with any global replica in the replica set, or any local or anonymous replica that the set created.
Local	Synchronizes only with its hub (global) replica.
Anonymous	Synchronizes only with its hub (global) replica.

Global	Replication Manager can schedule synchronization with any global or local (child) replica. Synchronization cannot be scheduled to anonymous replicas.
Local	Hub replicas can schedule an exchange to a local replica. And local replicas can schedule synchronization with their hub (global) replica.
