SAP router configration

Dears,

I am configuring saprouter.Till the step of import certificate everything went perfect and test of import certificate was correct.

Now in the steps i found i should be having saprouttab file but i searched in whole computer but didn't find the file. Please tell where this file is located or i have to create this file manually as SAP also has provided us a example of saprouttab file.

Please suggest.
