US Patent 11436037 Learning of tunnel endpoint selections

Some embodiments provide a method for a managed forwarding element (MFE). At the MFE, the method receives a first packet from a particular tunnel endpoint. The first packet originates from a particular data compute node associated with multiple tunnel endpoints including the particular tunnel endpoint. Based on the first packet, the method stores an association of the particular tunnel endpoint with the particular data compute node. The method uses the stored association to encapsulate subsequent packets received at the MFE and having the particular data compute node as a destination address with the particular tunnel endpoint as a destination tunnel endpoint.
