This course will give you clear concepts in static and default static routing.
For this particular course, I am using Cisco IOS routers.
To make the concept clear, I have used seven internal routers and one external router.
There is also a loopback interface on external router that represents a remote host/server.
If you have any doubts in subnetting, please refer to my course Subnetting in IPv4 | Udemy
Because this is a large network and we are configuring the same thing again and again, you will find that by the end of the course, you have learned the concepts and probably there may not be need to spend more time on static and default static routing configurations. Of course, you will have to study this course with full concentration in order to save your time after the course. This is not rocket science, it’s just same configurations, but on different devices and in different directions.
Feel free to clear your doubts in the QA session provided by Udemy. I will try my best to answer your questions so that your doubts are crystal clear.
Please read the file on basic to intermediate configurations in Cisco IOS Routers. If you need more configurations, please let me know, I will try to add them.
All the best.
