Notes: Often in BGP a manual summary is used (a Static route to Null0, and inserting to BGP table via Network command) EIGRP summary route has AD 5, so it will overwrite everything in RIB except static/connected routes. It may have unexpected effects with a very general mask, or if you want to advertise a Default route using the summary A quick shortcut: Check the smallest power of 2 containing the number of subnets. The Exponentiation will be the minimum of bits you have to subtract from the mask E.g. if you want to summarize 12 networks you have to use 4 bits (the lowest possible number is 16, which is 2^4), but also you will summarize more networks than only 12
Hi Charles! please lemme know what program you are using to draw your topology like one appearing on your video. I am studying my CCNP/CCIE certification, and document it on a blog ... will be useful to use some topologies like yours. Cheers!!!
Due to my background in graphic design and familiarity with the software, I actually use Photoshop to make all of my topologies. I use the official icons provided by Cisco that you can find here: bit.ly/3ixnlWI. You can also use those icons to create topologies in PowerPoint, Keynote, or even Notepad. There are lots of dedicated network design software options available, both paid and free. If you're looking for a free option I would have to recommend app.diagrams.net.
Again a very simple way to teach the content, please keep it up!!
Thank you sir for such a wonderful explanation
Thanks for sharing your knowledge and experience!
Great Stuff Charles.
love your videos CJ
