CASE ANALYSIS

Scenario

This diagram illustrates a network design using two routers to segment office and guest Wi-Fi traffic via VLANs, ensuring secure and isolated network access.

Key decisions

  • Using dual routers for redundancy and VLAN isolation
  • Assigning VLAN 10 to office and VLAN 20 to guest traffic
  • Implementing trunk links between routers, core switch, and access switch
  • Placing access points and clients in access VLAN ports

When to reuse this

Use this diagram when designing a small to medium-sized network that requires separate network segments for internal and guest users, with high availability through redundant routers.
