Episode 4: Legacy Inter-VLAN Routing

Scenario: A company's network uses a legacy router (RouterA) to route traffic between three VLANs: VLAN7 (Sales), VLAN17 (Marketing), and VLAN77 (Engineering). Each VLAN has a separate subnet: 10.136.0.0/13, 10.144.0.0/13, and 10.152.0.0/13 respectively. The legacy router uses a static routing configuration. Legacy inter-VLAN routing refers to methods of routing network traffic between different VLANs (Virtual LANs) using older technologies and equipment that are no longer considered best practice. These legacy methods often present challenges in terms of scalability, security, and manageability compared to modern approaches.
