Lab 4‐3: Simple 2‐Network Packet Tracer Lab - Lillian-Griffiths/NET-150 GitHub Wiki
In this lab, I created two networks linked by a router. I tested connectivity by pinging devices on the opposite network.
Simulation mode is a packet tracer tool that allows you to view the network traffic on the network, step-by-step. It also allows you to filter for certain events, such as specific protocols being sent over the network. Additionally, it has visuals for packets being sent over the network, to allow you to see where packets are at any point in time.
To save a router configuration, simply go into the config tab, and click "Save NVRAM." The router configuration has now been saved, and will persist after a reboot.
Some useful packet tracer tips are:
-
Use simulation mode if a ping or other tool isn't working, as it will allow you to see where the packet is getting stuck.
-
The fast forward button in real time mode can skip through certain events that take a while, such as a device restarting.
Issues I faced in the lab:
- I couldn't establish connectivity between the router and the switches. This was solved by figuring out that each port on the router is set to down by default, and they must be turned on manually.
