rp-mapping shows the complete 'database': which groups are mapped to which RPs (using static rp, or auto-rp advertisements that the switch has detected).
You use this command to verify if the switch has successfully received the RPs via auto-rp
You can determine the rp of your group by looking through this messy table yourself, OR
you can use the "sh ip pim rp <group>" to do the same for you.....
