Hello,
I'm preparing myself for JNCIP-SP. I would like to setup multicast network using LSYS with vMX. Multicast sender & receiver will be also LSYS. The network diagram look like shown below :

Assume that R5 & R6 are members of multicast group 224.0.7.7.
I configured PIM spare mode in R1,R2 & R3 interfaces. R2 is RP. My concern is to know which configuration required so that multicast traffic could flow from R4 to R5 & R6.
