[f-nsp] Multicast causing high CPU

[spenserhuang at aptg.com.tw]

Dear Sir:

No, It just like forward the multicast as layer 2. You better not use Bigiron 4000/8000/15000 or Netiron 400/800/1500 as igmp snooping. 

Those platforms have limit memory and cpu power. I have test Netiron 400 before and saw mosaic in MPEG2 video. The Bigiron RX, 

Neiron MLX, XMR are much better for multicast. You may check the following address for more information.
