Examples herein are directed to centralized database based multicast converging. For instance, in various examples centralized database based multicast converging can include starting a restart timer having a value greater than a time to validate stored entries in a centralized database, sending data packets at least to hosts on the network corresponding to the stored entries in the centralized database to maintain service to the hosts while the restart timer is running, sending query packets to validate a host corresponding to an entry of the stored entries in the centralized database, and responsive to the restart timer expiring, sending data packets to a converged group of hosts including at least the validated host.
