I just killed the PVC of a DSL customer that was sending exactly 115
DHCP DISCOVER messages per second. That caused a 600% increase on the
CPU of the NPE-G1 that the PVC terminates on and the DHCP is currently
being run on. Are there any DHCP rate-limiting features built into the
IOS that could be used to throttle either how often the router will
respond to certain received queries, to queries from a single host, or
the rate at which queries can be punted to the CPU for processing?
