Important Troubleshooting Commands
show ip route (Show you routing table of a router)
Tracert 30.0.0.2 (Destination address) (shows you the route to reach the destination. this command only works in PC)
no ip route 20.0.0.0 255.0.0.0 192.168.1.2 (To delete route, just add no before the routing command. here route is, "ip route 20.0.0.0 255.0.0.0 192.168.1.2")
show running-config (Tells you all the configuration and commands that run on the router but these configurations are not permanently saved and it is available on RAM)
Show startup-config (Tells you all configurations and commands that are permanently saved in NVRAM)
Write (command used to configurations in NVRAM)

What is a broadcast domain?
A broadcast domain is a collection of network devices that receive broadcast traffic from each other.
What is a collision domain?
The collision domain is a term that is not so obvious for most people that are new to networking. It is something that we had to deal with a long time ago, a time where we used older Ethernet standards and hubs instead of switches.
A collision domain is a network segment with two or more devices sharing the same bandwidth. (Where there is a chance of collision)
Find the number of Broadcast domain and Collision domain in a network.
Find the number of broadcast domain and collision domain
This is another example of how to find the number of collision domain and broadcast domain.
