Setting Up Reverse Invoke Connections with SAProuter 
SAProuter can be used as both a client and a server for reverse invoke (RI). Since SAProuter releases are independent of SAP kernel releases (SAP NetWeaver Application Server), reverse invoke can also be used with older releases of SAProuter by interconnecting two SAProuters.
Procedure
Starting SAProuter with RI
To activate reverse invoke for SAProuter, you start the SAProuter as follows:
saprouter -i <RI config file> other options]
All settings for the SAProuter are made in a configuration file. The options in this file affect the connection setup only, all other SAProuter functions remain the same.
SAProuter Configuration Parameters
The configuration parameters listed in the configuration file are described below.
The parameters can be divided into client and server parameters. Some appear both as RI clients and RI servers for the SAProuter.
