1) In a true sense the broadcasting (or data distribution) replication involves sending data changes from one source to multiple targets, using the

    same source Shareplex instance. In this kind of setup, the source and target use the same port number to communicate.

2) There is an alternate way by which replication can be configured so that the source server has multiple instances of Shareplex, each   

     replicating to a different target server using different port.

     For example:

     one can create a source instance on port 2100 to replicate to one target that is also configured to listen on port 2100, create a second source

     instance on port 2200 to replicate to the second target that listens on port 2200, and so on.

This solution delves on the preferred way out of the two to achieve this.
