The name of the database being published. @publisher_db is sysname, with no default.
[ @redirected_publisher = ] N'redirected_publisher'
The AG listener name associated with the AG that will be the new publisher. @redirected_publisher is sysname, with a default of NULL. When the AG listener is configured to use a non-default port, specify the port number along with listener name, such as ListenerName,51433.

Remarks
sp_redirect_publisher is used to allow a replication publisher to be redirected to the current primary of an AG by associating the publisher/database pair with an AG's listener. Execute sp_redirect_publisher after the AG listener is configured for the AG that contains the published database.
If the publication database at the original publisher is removed from an AG at the primary replica, execute sp_redirect_publisher without specifying a value for the @redirected_publisher parameter to remove the redirection for the publisher/database pair. For more information about redirecting the publisher, see Manage a replicated Publisher database as part of an Always On availability group.
Permissions
Caller must either be a member of the sysadmin fixed server role, the db_owner fixed database role for the distribution database, or a member of a publication access list for a defined publication associated with the publisher database.
