- Hey there, are you trying to break into cybersecurity but feel like you don't know where to start? Or do you feel like your working hard but its not getting you in?
My name is Chris Ray and I help people break into Cybersecurity by focusing on all the skills needed to land your first cybersec job (or move up!).
Subscribe to my channel, I post videos weekly on a variety of topics I am certain will level-up your cybersecurity game!
Reverse Path filter or Reverse Path Failure (aka RPF) can be a tricky concept to grasp. In this video I provide some examples with short, concise explanations that will help you understand what RPF is and why we use it.

man... do you have any idea how LOOOOONG!!!!!!! i've been looking for a clear explanation. So many folks on here (youTube) make it difficult to understand....geez. thank you so much.
I'm glad you went with a diagram because I think it lands so much better than I can imagine a demo would. I got a question on the NSE4 on RPF and yours was the first video that made sense.
Wow. This was good, Chris! Very simple explanation. Thank you.
Thanks Robert, its a remarkably simple concept...just not easy to grasp!
A few people have asked how it works with a default route. In feasible/loose mode it will be no different for a default route. The default route counts as a valid route. Source: NSE4 study guide.
The most easy explanation on RPF ever, thank you very much sir!
This helps with refreshing nse4 knowlegde for NSE7 cert :)
Fantastic Vid! A clear and concise explanation... this really helped me understand RPF. Thanks Chris.
Hey Anthony, glad it helped! RPF had me running in circles when I first ran into it. I had to make a video about this :)
Another great video. Thank you, Chris!
Thanks for the easy and clear explanation!
Very easy to understand .. Great explanation.
Great explanation. Just what I was hunting around for. I wonder though, what impact does a default route have route matching?
Got if!
Thank you 😊

Hi Chris ,my doubt is when a default route to internet like Destination=0.0.0.0/0 and exit interface wan .How the RPF will work here ,for example the fortigate have a default route to internet like this
set status enable
set dst 0.0.0.0 0.0.0.0
set gateway 218.208.110.1
set distance 10
set weight 0
set priority 0
set device "wan2"
good video. pls make more for the lab setup used in previous video's. also are there books you used to pass the exam?
I used the free training that you can get from the NSE Institute. I don't think there are any books on this cert yet, but I could be wrong.
Ok cool i will use that also. Could you do some basic firewall and maybe some advanced stuff and could you do traffic shaping? I will need to know it for a job im starting next month
@@shom3rshabbos Hell yeah man! Lets see what we can do...
Can you recommend a good book for the ns4?

Not clear or helpful and wastes too much time at the beginning .
