What is ip route cache?
What is ip route cache?
The route cache allows outgoing packets to be load-balanced on a per-destination basis. The ip route-cache command with no additional keywords enables fast switching. Our routers generally offer better packet transfer performance when fast switching is enabled, with one exception.
What is ip route flush cache?
Since the kernel refers to the routing cache before fetching a new route from the routing tables, ip route flush cache empties the cache of any data. Now when the kernel goes to the routing cache to locate the best route to a destination, it finds the cache empty.

What is router CEF?
Cisco Express Forwarding (CEF) is a packet-switching technique used within Cisco routers. The main purpose of CEF is to optimize the forwarding of packets and increase the packet switching speed.
