What is Packet Tracer?
Packet Tracer is a standalone, medium-fidelity, simulation-based learning environment for networking novices to design, configure, and troubleshoot computer networks at a CCNA-level of complexity. Packet Tracer supports student and instructor creation of simulations, visualizations, and animations of networking phenomena.
Like any simulation, Packet Tracer relies on a simplified model of networking devices and protocols. However, real computer networks remain the benchmark for understanding network behavior. Packet Tracer was created to help address the “digital divide” in networking education, where many students and teachers lack access to equipment, bandwidth, and interactive modes of learning networking.
Note: Let me assume you have some knowledge on routing.
LET US CREATE TOPOLOGY AND CONFIGURE DEVICES AS SHOWN IN DIAGRAM
(Click on image to enlarge)
PROCEDURE TO CREATE TOPOLOGY
- Start Packet Tracer
- Click on Routers in left bottom and drag 3 router model called 2621M onto the workspace
- Above model have 2 fast Ethernet ports.
- We have to add WIC-2T module to the router
- Switch off the router and drag the module in given 2 places in router back panel.
- WIC-2t Module:
The 2-port asynchronous/synchronous serial network module provides flexible multi-protocol support, with each port individually configurable in synchronous or asynchronous mode, offering mixed-media dial support in a single chassis. Applications for Asynchronous/Synchronous support include: Low speed WAN aggregation (up to 128 Kbps), dial-up modem support, Async or Sync connections to management ports of other equipment, and transport of legacy protocols such as Bi-sync and SDLC.
- Connect all routers using connection medium. Select automatic medium so that serial ports can be used.
- Assume center router be ISP side router and remaining 2 as Mumbai side router and the other as Delhi side router.
- Drag the switch of type 2960-24TT as shown.
- Drag the generic hosts and connect all of them.
- Now the topology is created like shown.
- Red dots indicate down-state and green dots indicate up-state.
