Just question in regard to the rib and fib &amp;&nbsp;process swithching and cef. For example say we have ospf and eigrp on same router nothing else no statics. Does all routes i.e the topology table in eigrp and the link state table in ospf (i.e all routes best and worst of both protocol routes) populate the routers rib table. Then the routers fib table is made up of face off between routes in the ospf forwarding table vs routes eigrp routing table(i.e the best routes in both). With eigrp winning in default config because of the lowest admin distance and populating the fib tbale. &nbsp;<br />
<br />
Then difference between process switching and cef. Is that process switching ques and searches the rib table for the best route taking more time + processing. While cef works of the scaled down fib table speeding up the switching speed of the router??<br />
<br />
Can someone confirm this is correct or explain?<br />

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
