<div dir="ltr">Hi<br><br>I've got a customer who's seeing very high CPU utilisation whenever multicast is turned on across his BigIrons. I'm sorry I can't be<br>more specific than this, it's just about all the info I have. They also have cisco 3750s and 65s which seem to be doing fine. Before I can<br>
get a chance to look at the topology, I'm thinking about maybe rpf checking owing to a split l2/l3 architecture, or possibly just the RP functionality<br>being too much for it (decapsulating PIM registers).<br><br>Are there many multicsat users on this list? And for that matter, are there any good high cpu utilization troubleshooting guides out there<br>
for foundry?<br><br>Thanks!<br>Christian<br></div>
