Multicast PIM Designated Router

Its seems relatively straightforward when explained. However, may become less so when starting to apply in real world :slight_smile: . One real world example - client is facing redundant pair of routers with HSRP. Will both routers still participate in DR election? How its going to work then if router with lower IP is the active router? Looks like the joins may not be sent as DR (being passive) will not receive client request and active router will receive it but will not send join to RP, since its not a DR. If thats the case does it mean in HSRP case (which is very often) we always need to manually increase priority on the active router to make it DR and ensure registration with RP?
