Hub-and-Spoke VPN Topology

Analyze a real-world VPN configuration scenario and identify the correct network topology.

Lab Environment

Scenario

Brandon configured a VPN setup where all remote offices securely connect to a central corporate office. However, direct communication between remote offices is not allowed.

✔ Remote offices → can connect to HUB
✖ Remote offices → no direct communication
↻ All communication flows through the central hub
Challenge

Which VPN topology is used in this scenario?

💡 Look for a central hub controlling all communication.
Knowledge Base

Mini Lesson

1
Definition: A Hub-and-Spoke VPN topology connects multiple remote sites (spokes) to a central hub.
2
How it works: All communication between remote sites passes through the central hub, which manages and controls traffic.
3
Why it matters: It simplifies network management and improves control but may introduce a single point of failure.
4
Real-world example: A corporate network where branch offices connect to headquarters but not directly to each other.
5
Key takeaway: Hub-and-Spoke = centralized communication through a hub.
