Multiple WebpartProviders to one single WebpartConsumer

According to the user Rhys in this post Sharepoint multiple connections to a w开发者_如何转开发eb parts you need to configure your providers to point to a specific consumer method. How do i do said configuration to the providers?

Web part connections are very loosely coupled. The provider part exposes a method, marked with the ConnectionProvider attribute, that indicates it can provide information defined by a specific interface. The consumer part exposes a method, marked with the ConnectionConsumer attribute, that indicates it can consume information defined by a specific interface. When the provider and consumer use the same interface, they can communicate with each other. The communication is managed by the WebPartManager, not the web parts themselves.
