Deep down inside, I'm thinking that this cpu busyness as the tcam gets reprogrammed with 500k entries all at once might just be expected behavior on the sup720.
Presumably the problem isn't the CPU being busy per-se, but the fact that, during the very slow FIB loading, the (progressively decreasing) absence of TCAM entries is causing traffic to punt to CPU?
I'm kind of a bit puzzled by this; it's not entirely obvious to me why enabling the specific sequence of commands would cause a complete "wipe & refill" of the FIB, as opposed to an incremental update.
