I heard, that I can enable "route-chache" or similar, to reduce the CPU load. Is this right? How should I configure it on a 3750G.
CEF is faster, less CPU-intensive and provides superior performance compared to other switching technologies, especially in networks with dynamic traffic patterns. It supports per-source-destination and per-packet load balancing. This is a major advantage over route-cache switching mechanisms like fast switching, where route caching needs to be disabled for per-packet load balancing to work. CEF support in Cisco IOS is version and platform dependent.
