This past week I've been learning more about static routing and about how routers handle , packets. The Internet spans across the entire globe, from America to Thailand to Antarctica, , connecting all of us. To transfer data across this massive network there are variety of devices , installed in critical locations; some of these devices include: routers, primary switches, core , switches, servers, databases, and more. I learned about what routers were and what they did. , Routers are devices that connect multiple networks and determine the fastest most trustworthy , route for a packet to take to its destination. There are a few protocols routers use to determine , the best path some like EIGRP and OSF; each of these protocols prioritize different factors like , bandwidth and latency to determine the best route. Each routing method has a certain , administrative distance; administrative distance uses metrics to describe the trustworthiness of a , network in a numerical value (the larger a number is the greater distance it has and less , trustworthy it is). Routers also use a routing table to determine a path for a packet; a routing , table is table that shows a list of known networks, the best way to reach a host on that network, , and other information about the path. But many times the network a host is trying to , communicate isn't a nearby or local network that isn't in the routing table, in these situations , routers either drop the packet or use a static route if configured. Static routes are paths , configured for remote locations and need to be manually updated if the network changes. Static , routes can also be configured to act as a default gateway for the router for packets that aren't in , the routing table. Overall this week I've learned about the function of routers and static routes.
