Configuration of Routers In Cisco Packet Tracer Routing is a process which is performed by layer 3 (or Network Layer) devices in order to deliver the packet by choosing an optimal path from one to another. Static Routing-        Static Routing is a process in which we have to manually add a router in a routing table.       Advantages- No Routing overhead for router CPU which means a cheaper router can be used to do routing. It adds security because the only administrator can allow routing to a particular network only. No bandwidth usage between routers.        Disadvantages- For a large network, it is a hectic task for an administrator to manually add each router for the network in the routing table on each router. The administrator should have good knowledge of the topology. If a new administrator comes, then he has to manually add each route. CONFIGURING ROUTERS: Connect the PCs with the switch through copper straight through cable by inserting i

STUDY OF BASIC COMMANDS OF CISCO PACKET TRACER ENABLE : To enter privileged EXEC mode or any other security level set by a system administrator, use the enable EXEC command.                              Syntax: >> enable [priviledge level]                                           ---> privilege level: optional CONFIGURE TERMINAL/ config t: Enter the global configuration mode, when using the console part.                               Eg. >> enable                                     >> config t                           (config)# EXIT: To exit any configuration mode to the next highest mode in the CLI mode hierarchy, use the exit command in any configuration mode.                              E.g. >>exit INT FA 0/0 OR 0/1: The notation is denoting that there are multiple NIC interfaces on the switch/ router. ' fa' indicates that the NIC port is most likely a fast ethernet type of connection.
