Network Router Components
ROM: Store the Routers bootstrap details, operatingsystem software.Flash Memory: Holds the operating systems images. Thecontent is retained when the Router is restarted.RAM: Store the Routing tables, configuration files, cachingand buffering details. Content is LOST when lost router isswitched off or restarted.NVRAM: Stores the Routers startup configuration files.Data is NON volatile.Network Interfaces: Connect Router to Network.
Let’s See The Components!!!

IntroductionRouting Basics
Routing BasicsRouting Definition: In internetworking, the process ofmoving a packet of data from SOURCE to DESTINATION.Routing is usually performed by a dedicated device calleda ROUTER.Types of Routing: Dynamic Routing and Static Routing.Routing Table: Contains a list of specific routingdestinations and when the Router receives a packet ofdata it references the Routing Table to know where to sendthat data.
See The Routing Tables :
1. Cisco Routers IOS: show ip route2. Linux OS: route -n3. Windows OS: route print, netstat -rn

Routing Algorithms
Routing algorithm determines the best possible path(next hop) and update the Routing Table.
Examples of Routing Algorithms :1. Bellman-Ford Algorithm2. Dijkstra’s Algorithm3. The Floyd Warshall Algorithm4. etc.
