Controlling Multicast stream on SRX enabled for PIM DENSE MODE

Hi everyone,

Please consider the following set up:

S-----f1 SRX1—f2------WAN-----f2SRX2—Receiver (239.2.2.2)

Above we have multicast source sending traffic at 239.1.1.1, SRX 1is running PIM dense mode all interfaces including f2.

Only f2 is shown for brevity

Our issue:

All traffic destined to 239.1.1.1 is flooded out of F2 where it gets pruned as there is no receiver off that interface. It consumes slow WAN bandwidth.

Can we do this? (Assume we cannot use SPARSE MODE)

Apply filter that egress on F2 on SRX1 that denies all traffic destined to 239.1.1.1?

Thanks and have a nice day!!
