15. A controller bridge implemented in a computer network and configured to implement mechanisms for dynamically exchanging runtime state data between datacenters, the control bridge comprising:
one or more processors;
one or more memory units; and
one or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving, by the controller bridge, one or more first runtime state data from one or more logical sharding central control planes (“CCPs”) controlling one or more logical sharding hosts;
receiving, by the controller bridge, one or more second runtime state data from a gateway that is controlled by a CCP that also controls one or more physical sharding hosts, wherein the one or more second runtime state data received from the gateway comprises a mapping between virtual network identifiers (“VNIs”) and a gateway remote tunnel endpoint (“RTEP”);
aggregating, by the controller bridge, to aggregated runtime state data, the one or more first runtime state data received from the one or more logical sharding CCPs and the one or more second runtime state data received from the gateway;
determining, by the controller bridge, updated runtime state data based on the aggregated runtime state data, the one or more first runtime state data, and the one or more second runtime state data; and
transmitting, by the controller bridge, the updated runtime state data to at least one of the one or more logical sharding CCPs and the gateway.
