This comprehensive guide breaks down the core requirements, structural architecture, configuration steps, and security protocols needed to successfully complete the Revision B case study. Scenario Overview and Network Requirements : The headquarters router, frequently used to handle

Apply OSPF configs and confirm neighbor adjacencies using show ip ospf neighbor .

: The first usable IP address in a subnet range is reserved for the local router interface acting as the Default Gateway.

On each switch, create VLANs as per case study requirements (e.g., VLAN 10 – Sales, 20 – Eng, 99 – Native).
