Yes, those are not HW switched but punted to CPU in order to generate TTL_Exceeded ICMP message. Not sure if there's any knob to discard them silently. > Just out of curiousity, would adding "ip multicast ttl-threshold 3" Beware, this is real evil. On most switch platforms this will completely disable HW forwarding of multicast packets and punt them *all* to CPU.
