In this design we have a network similar to what we would see in real life in big organizations. Here we have 8 subnets out of which we use 5 of them. Large networks are often valnurable to component failures. In this example if the main switch fails then the whole network will be unable to communicate with themselves or the outside world. This is why we have 2 main switches so if one of them fails, the network will still be functional. Same thing can also be done for the router. Note that all subnets in this example can communicate with each other with static routing configured on their interfaces. If it's maximum security that we are after then we should avoid this because if one subnet gets infected the attack will spread to the others. To prevent that, we isolate each subnet so it can only communicate with the internet and not the other subnets.

IOT Network
IOT stands for Internet Of Things and it's a critical innovation that we have in our service today. Basically, every day devices can connect to your home network and communicate with your mobile device giving you the ability to control them without being home. This helps if you want to preheat the water on a cold winter day or turn on the AC remotely. This is what this project is based on since you can turn on and off all home appliances with the smartphone.

This design features a functioning web server that hosts a website that any user from network 1 (right) can access. Network 2 (left) also has a DNS server that helps the user find the website by typing in its domain name than the ip address of the website. The 2 routers communicate through RIP routing configured on their CLI panel and also act as a DHCP server for their network.

2 subnets
This network has been split in half and has created 2 smaller subnets. This process is called subnetting and is very useful in networking because you can organize your networks better and save valuable ip addresses you can use elsewhere. Also it adds an extra level of protection because you can isolate your subnets so they can't communicate with each other and as a result in the event that someone hacks into one subnet he will not have access to the other one immediately.

This is a common home network that has both wireless and wired devices connected to it. The router acts as a DHCP server and as the default gateway for the other devices to connect to the internet.
