R4 is directly connected to both RPs, R2 and R3. R4 is presently sending all joins upstream to R3, but you want all joins to be sent to R2 instead.
Referring to the exhibit, which configuration change resolves this issue?
PIM group-to-RP mappings are controlled by the advertised group ranges. R3’s 224.1.1.0/28 range is more specific than R2’s 224.1.1.0/24, so it is selected for groups in that range. Configuring a more-specific group range on R2 makes R2 the selected RP; RP priority and the unicast next hop do not override that group-range mapping. Juniper: group-ranges
224.1.1.0/28
224.1.1.0/24
