The is a comprehensive practical assessment within Cisco's Switching, Routing, and Wireless Essentials (SRWE) curriculum . It presents a realistic corporate merger scenario between the Carl I. Samson Company (C.I.S. Co.) of Bangor, Maine, and a newly acquired entity called Big-Corp , which operates across branch offices in Phoenix, Arizona, and Chicago, Illinois.

Phase 2: Inter-VLAN Routing and Edge Gateway ccna-2v7.0 case study -rev b-
Before advanced features are added, you must harden each network device: Initial Settings
To allow traffic from all local VLANs to reach the gateway router, configure the interconnection interfaces as IEEE 802.1Q trunks. Change the default Native VLAN from 1 to to eliminate potential VLAN-hopping attacks.
. This wasn't just a lab; it was the final blueprint for the Oakhaven University The is a comprehensive practical assessment within Cisco's
core. But there were complications. The Dean insisted on total isolation for the research data, while the Student Union needed open Wi-Fi that wouldn't bog down the registrar’s office. Alex looked at the topology. It was a classic "Rev B" mess: VLANs 10, 20, and 99 were already saturated. The new wing required DHCP relay because the central server was three hops away. Inter-VLAN routing had to be handled by a new Layer 3 switch , replacing the aging "Router-on-a-Stick" setup. 2. The Implementation: Trunking and Tensions
Here's a step-by-step guide to help you complete the case study:
Requires localized infrastructure mapping, secure routing, and access point provisioning. 🗺️ Phase 1: IP Addressing and VLSM Design replacing the aging "Router-on-a-Stick" setup. 2.
The CCNA-2v7.0 (Routing and Switching Essentials / Switching, Routing, and Wireless Essentials) Revision B case study typically models a medium-sized business expanding its operations. The organization requires a scalable, secure, and redundant network design spanning multiple floors or physical buildings. Key technical domains tested include:
Administrators must split a physical router interface into subinterfaces corresponding to each VLAN:
