DR in multicast

Hi there is a Designated router(DR) between RP and receiver. Looks like there is also a DR between source and RP. are the both DR same thing? thanks

Hi

 "...When we configure PIM on our routers, we will establish PIM neighbor adjacencies, and the PIM hello messages are also used to elect a designated router for each multi-access network. The DR is the router that will forward the PIM join message from the receiver to the RP (rendezvous point)..."

@Flavio Miranda thanks for your reply. The article below also talks about the issue. so that DR also handle relation between source and RP, but it is different function.
