<br>
Well, I'd like to bring this thread up again hoping to catch<br>
someone who has also hit this issue.<br>
<br>
Today I upgraded software to 05.9.00be, and situation is still<br>
the same: with enabled Multicast Traffic Reduction,<br>
multicast traffic is being switched by LP CPU.<br>
<br>
Current test VLAN configuration is:<br>

Right after multicast stream start flooding from Eth11/2 out of TR(e9/5,e7/1),<br>
the CPU load on LP 11 increases:<br>

I have no ideas why it happens. "Multicast Guide" clearly tells<br>
that these packets should be processed in hardware.<br>
Please advice!<br>
<br>
Thanks!<br>
