Just question in regard to the rib and fib & 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.
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??
Can someone confirm this is correct or explain?
