With Auto-RP, the Mapping Agent selects the RP for a specific group based on
the Highest IP Address. All Mapping Agents (if you have redundant ones
configured) will send out the same RP-to-Group mapping information. So, the
RP with the Highest IP address is "active" and the other RP is simply
standing by.
Should the "active" RP stop sending updates, when the RP-to-Group mappings
time out, the Mapping Agent will then advertise the "standby" RP as "active"

Ya i got you question wrongly! I did send another email saying that there is
no back RP in AutoRP mode unless you use MSDP which is quite lengthy
process. Also, that's an Active-Active back RP, kinda loadbalancing! of
course, if one RP fails then the other will back it up!
GS Guys, please correct me if i'm WRONG!
Best Regards,
