In this video, I dive into common network architectures and discuss where you will find them along with the features, benefits of the different styles.
How would you choose the leaf switch that connects the outbound traffic? Any of them could be used, since they are all interconnected through the spines. MAtter of fact, why not use one of the spines, since these are usually beefier switches ( I would assume)?
For each VLAN you would need to identify the number of devices on that VLAN that need an IP address. From there you can choose from one of the private IP ranges and allocate a subnet that has enough IPs to meet the demand of that VLAN.
If I were tasked with building out a network for multiple car dealership locations, I would look at the network needs for each location, then build out network architectures for each location. Then, connect the multiple locations together with an SD-WAN solution.
The diagrams are very uninformative, needs much better labeling and perhaps bullets in a follow up slide for crisp use cases, advantages, disadvantages, etc.
