Since I can't directly generate images or diagrams, Iβll provide a text-based representation of a multi-level network, including devices and their connections. You can use this as a guide to create a visual diagram using tools like Microsoft Visio, Lucidchart, Draw.io, or even PowerPoint.

-
Internet:
- Web servers, DNS servers, cloud services, and the ISPβs border router.
- Connected via BGP (Border Gateway Protocol) for routing between autonomous systems.
-
ISPβs Core Network:
- Uses BGP and OSPF to route traffic within the ISP and to the internet.
-
Corporate Network:
- Firewall: Protects the internal network and performs NAT (Network Address Translation).
- Core Switches (Layer 3): Route traffic between VLANs and subnets using OSPF or static routes.
- Distribution Switches (Layer 3): Aggregate traffic from access switches and route between VLANs.
- Access Switches (Layer 2): Connect end devices (workstations, servers) and forward traffic based on MAC addresses.
-
End Devices:
- Workstations, servers, and other devices connected to access switches.
- Internet to ISP: BGP peering between the ISPβs border router and external networks.
- ISP to Firewall: Public IP assigned by the ISP to the firewallβs WAN interface.
- Firewall to Core Switches: Internal routing using static routes or OSPF.
- Core to Distribution Switches: OSPF or static routes for inter-VLAN routing.
- Distribution to Access Switches: Trunk ports carrying multiple VLANs.
- Access Switches to End Devices: Standard Ethernet connections.
| Connection | Protocol/Technology Used |
|---|---|
| Internet to ISP | BGP |
| ISP to Firewall | Static routing or BGP |
| Firewall to Core Switches | OSPF or static routes |
| Core to Distribution Switches | OSPF |
| Distribution to Access Switches | VLAN trunking (802.1Q) |
| Access Switches to End Devices | Ethernet (Layer 2 switching) |
- Use a diagramming tool like Draw.io, Lucidchart, or Visio.
- Start with the Internet at the top.
- Add the ISPβs core network below the internet.
- Draw the corporate network below the ISP, including:
- Firewall
- Core switches
- Distribution switches
- Access switches
- End devices
- Use arrows to represent connections and label them with the protocols used (e.g., BGP, OSPF, VLAN trunking).
