Hi, sarahr202! RP was on R3 in topic starting post. And you posted configs for modified network with RP on R2. However, with posted configs, RP on R2 and testing client on R3 all should be fine. Do you still see duplicating starting packet?

Hi sarahr202,   I think you are confused yourself and tries to confuse readers. :)   All that you posted might be normal behavior or might be a bug. It might be wrong configured devices or wrong network engineering or bug (I doubt in it) or all works...
