If so, that prefix is added to the routing table, with the advertising router as the best next hop.
CISCO RECEIVER COUNTING DOWN LETTERS AND NUMBERS UPDATE
When a router receives an update or change, it checks its routing table to see if the update contains an advertised prefix that was previously unknown. After it’s converged, the routers do not necessarily have identical routing tables, but they are consistent and correct. Once all routers have learned their best paths to all available prefixes, the network is “converged”.

If so, those additional paths would be tracked in other behind-the-scenes data structures separate from the routing table. A routing table entry always represents the best known way to reach a particular prefix, the router may be aware of other possible paths to that prefix. For exampleįor each prefix displayed in the routing table, the entry will indicate how the route was learned the next hope router’s address and outbound interference used to reach it and other information. But keep in mind that a prefix is a particular address/mask combination. Each entry in the routing table gives the best way for that router to reach a particular IP prefix. You can display IP routing table for available routes with the command show IP route. In common word, a route is an entry in the IP routing table.

But first, let’s define what we mean by route. In this blog we will discuss about routing and routing protocol.
