I had done following things:
any help how to configure i.e. steps to configure this replication agent
I don't want to offend you but Can read the requirements mentioned here https://docs.adobe.com/docs/en/aem/6-1/administer/integration/marketing-cloud/target/target-requirem...
Go to the "Enabling the Target Replication Agent" and I am sure you will be able to understand what i am talking about.
this agent is responsible for publishing the target campaign and segment from AEM to Target.
