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 switc...

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...

Introduction: Packet Tracer is a platform for visual representation/ simulation tools for Network development, developed by Cisco system, which allows users to create networks, and gives the privilege to configure routers, PCs and network devices through the virtual command line. Key Features: Packet Tracer Workspace:   Cisco Packet Tracer has two workspaces; one physical and another logical. The logical workspace allows users to build virtual networks by providing virtual switches, hubs, PCs, Routers and connecting devices as cables, connecting wires. Users can make virtual network topologies by placing, connecting the virtual network devices. The physical workspace shows the graphical representation of the logical network. 1. Logical Workspace 2. Physical Workspace Packet Tracer Modes:  Cisco Packet Tracer provides users with two operation modes to get the essences of the networks by visualizing the behaviour networks. One is Real Time Mode and an...
