The animated TECHTip Tutorial is available here.

This is a review of Cisco router switching modes. It is recommended that a review of Cisco’s router product line and a detailed understanding of the various router platforms such as small, medium and high-end routers be completed prior to any examination.

Cisco uses various types of switching caches to reduce switching delay. Distributed Switching is based on VIP [Versatile Interface Processor] cards which have onboard switching processors. With VIP, even the first packet does not go through the route processor to determine the switching path or route increasing router efficiency.
