Describe the IP routing process. You need to remember that the frame changes at each hop but that the packet is never changed or manipulated in any way until it reached the destination device (the TTL field in the IP header is decremented for each hop, but that’s it).
List the information required by a router to successfully route packets. To be able to route packets, a router must know, at a minimum, the destination address, the location of neighboring routers through which it can reach remote networks, possible routes to all remote network, the best route to each remote network, and how to maintain and verify routing information.
Describe out MAC addresses are used during the routing process. A Mac address will only be used on a local LAN. It will never pass a router’s interface. A frame uses Mac addresses to send a packet on a LAN. The frame will take the packet to either a host on the LAN or a router’s interface (if the packet is destined for remote network). As packets move from one router to another, The Mac addresses used will change, but normally the original source and destination IP addresses within the packet will not.
View and interpret the routing table all the router. Use the show IP commands to view the routing table. Each route will be listed along with the source of the routing information. A C to the left of the route will indicate directly connected routes, and other letters next to the route can also indicate a particular routing protocol that provided the information such as R, for RIP.
Differentiate three types of routing. The three types of routing are static (in which routes are manually configure at the CLI), dynamic (in which the router share routing information via a routing protocol), and default routing (in which a special row is configured for all traffic without a more specific destination network found in the table).
Compare and contrast static and dynamic routing. Static routing creates no routing update traffic and creates less overhead on the router and network links, but it must be configured manually and does not have the ability to react to link outages. Dynamic Routing creates routing update traffic and uses more overhead on the router and network links.
Configure static routes at the CLI. The command syntax to add a route is IP route [destination_network] [mask] [next – hop_address or are…
