When testing IGMP join rates I see an unusual rate of ~500pps. In an example I look at interface stats and see 1000 packets in, 539 input to local, 461 input to transit. Corresponding to this I see 539 IGMP groups setup. If I burst the same range again in the next second I don't learn any more. If I burst a new range of joins then these will go through.
This leads me to believe that there is some filter or DOS protection for multicast packets because looking at the CPU I only see ~10% utilization. I only see the default arp l2-policer being applied on this interface. Does anyone have experience with DOS protection in JUNOS?
