How do I know what type of topology should I use?
One of my network engineers always chooses Layer 3, his reasons are that Layer 2 creates much more broadcast and I am not entirely sure about this.
In which of these two will I spend more money on equipment. Which one is more heavily loaded?
I would like to understand when and what to choose, does this obey to type of traffic (audio, data, etc)? size of my network? Others.
