[j-nsp] Multicast/Broadcast Packets going to EX CPU

[Clarke Morledge]

Sebastian,

We are using a combination of storm-control and firewall filters, just to 
throttle the multicast back. Nothing special. Since we are not officially 
supporting multicast applications, this has not really hurt us yet.

Thank you for your reply,

can you share a bit more about what countermeasures you are
implementing? storm-control? firewall filters?
