The CCNA 2 v7.0 Case Study – Rev B successfully mirrors real-world networking challenges, requiring the integration of switching, routing, and security concepts. By implementing VLANs, trunking with a secure native VLAN, router-on-a-stick inter-VLAN routing, DHCP, static routing, and SSH, a network engineer builds a robust and manageable infrastructure. The case study emphasizes not just configuration but also verification and troubleshooting—essential skills for any networking professional. Ultimately, mastering these tasks prepares students for both the CCNA certification exam and practical network administration roles.
The CCNA 2 v7.0 (Switching, Routing, and Wireless Essentials) curriculum focuses on the architecture, components, and operations of routers and switches in small networks. Developing a case study for this specific version typically involves a scenario where a business must expand its network infrastructure to support multiple LANs and secure wireless access. Scenario Overview
You are a network administrator for a company called "E-MAGINE". The company is merging with another entity and expanding to a Wide Area Network (WAN) with multiple locations. Your goal is to design and implement a network that ensures inter-VLAN communication, secure access, and efficient routing. Core Case Study Components
A standard "Rev B" (Revision B) case study for CCNA 2 v7.0 should include the following modules: 1. VLAN and Inter-VLAN Routing
Objective: Segment the network for different departments (e.g., Sales, HR, IT). Requirements: Assign specific VLAN IDs and names (e.g., VLAN 10 - Sales). Configure 802.1Q trunking between switches.
Implement Router-on-a-Stick or Layer 3 Switching for Inter-VLAN routing. 2. Redundancy and STP Objective: Prevent loops in a multi-switch environment. Requirements:
Configure Spanning Tree Protocol (STP) to ensure a single loop-free path.
Optimize STP by designating a Root Bridge for specific VLANs.
Configure EtherChannel (Link Aggregation) to increase bandwidth and provide redundancy between switches. 3. Routing Concepts and Configuration Courses and training - PJATK GDAŃSK
In the CCNA 2 v7.0 Case Study - Rev B, a particularly interesting feature is the complex implementation of Floating Static Routes integrated with First Hop Redundancy Protocols (FHRP).
This scenario challenges you to move beyond basic static routing by configuring a secondary backup path that only appears in the routing table when the primary link fails. It specifically tests your ability to ensure high availability in a small-to-medium enterprise network. Key Technical Highlights
Floating Static Routes with IP SLA: This feature requires configuring an IP Service Level Agreement (SLA) to monitor the primary link's health. If the SLA probe fails, the floating static route—configured with a higher administrative distance—automatically takes over.
HSRP (Hot Standby Router Protocol) Integration: The case study often requires coordinating these floating routes with HSRP to provide a redundant gateway for end devices, ensuring that even if a router or link fails, the user traffic seamlessly transitions to the backup path.
Inter-VLAN Routing and Security: You must manage data flow between different VLANs while simultaneously applying Access Control Lists (ACLs) to secure the perimeter and internal segments.
Dynamic vs. Static Comparison: The case study forces a practical comparison between manual static route management and the automated discovery provided by dynamic protocols like OSPFv2, highlighting why certain environments might prefer the lower overhead of static routes despite their lack of scalability.
CCNA-2v7.0 Case Study (Rev B) a comprehensive network design and configuration project for the Switching, Routing, and Wireless Essentials (SRWE) . It centers on a corporate merger scenario where the Carl I. Samson Company (C.I.S. Co) in Bangor, Maine, acquires
, which has existing offices in Phoenix, AZ, and Chicago, IL. Scenario and Primary Goal
The core objective is to integrate the networks of these three geographically dispersed locations—Bangor, Phoenix, and Chicago—using a combination of IPv4 and IPv6 addressing and static routing Key Technical Components
The project is divided into phases that require the configuration of routers, Layer-3 switches, and end devices across the following domains: IP Addressing & VLANs:
Designing and implementing complex IPv4 and IPv6 addressing schemes. This typically includes configuring Router-on-a-Stick Layer-3 switching for inter-VLAN routing. Static Routing:
Implementing both standard and default static routes for both IPv4 and IPv6 to ensure end-to-end connectivity between all branch offices. Layer 2 Security: Hardening the network infrastructure by configuring Port Security ccna-2v7.0 case study -rev b-
, disabling unused ports, and setting up secure management access via IP Services:
Setting up pools on routers to assign addresses to LAN workstations.
Configuring stateless or stateful DHCPv6 for IPv6 address management. Redundancy and Reliability: Using protocols like Spanning-Tree (STP) for loop prevention and EtherChannel for increased link bandwidth and redundancy. Wireless LAN (WLAN):
Configuring a basic wireless infrastructure, often involving a Wireless LAN Controller (WLC) WPA2 security policies Project Deliverables
For this case study, students are typically expected to provide: Packet Tracer (.pka) File:
A fully functional network simulation containing all configurations. Addressing Table:
A detailed list of all interfaces, VLANs, and assigned IP addresses. Connectivity Testing:
Evidence (such as successful pings and traceroutes) that all hosts can reach one another across the unified corporate network.
The CCNA-2v7.0 Case Study (Rev B) is a comprehensive practical assessment within the Cisco Networking Academy "Switching, Routing, and Wireless Essentials" (SRWE) curriculum. It simulates a real-world merger scenario involving the Carl I. Samson Company (C.I.S. Co), which has expanded its Bangor, Maine headquarters by acquiring "Big-Corp" offices in Phoenix and Chicago.
This case study challenges students to integrate multiple core networking concepts into a single, cohesive infrastructure using both IPv4 and IPv6. Core Objectives and Requirements
The Rev B assessment focuses on several key technological pillars of the SRWE course:
Static Routing: Implementing primary and backup (floating) static routes for both IPv4 and IPv6 to ensure connectivity between geographic sites.
VLANs and Inter-VLAN Routing: Organizing local traffic into segments and configuring "Router-on-a-Stick" or Layer 3 switch SVIs for communication.
Switch Security: Applying best practices like port security, disabling unused ports, and configuring encrypted management access via SSH.
DHCP Services: Configuring routers to act as DHCPv4 and DHCPv6 servers to automate host addressing.
WLAN and Redundancy: Setting up Wireless LANs and ensuring network stability through EtherChannel and Spanning Tree Protocol (STP). Phase-by-Phase Implementation 1. IP Addressing and VLAN Design
In the initial phase, you must develop an addressing scheme based on specific user requirements for each site.
Phoenix (PHX): Typically requires sub-interfacing on the Phoenix router to support multiple VLANs (e.g., VLAN 120).
Chicago (CHG): Often acts as a central hub for specific services like DHCP.
Bangor (BAN): The headquarters router, frequently used to handle IPv6 DHCP pools (e.g., "DHCP-DNS"). 2. Basic Device Configuration The CCNA 2 v7
Security is a priority from the start. On all routers and switches (like CHG-RTR, PHX-SW-1, and BAN-RTR), you must:
Secure the IOS: Encrypt all passwords, set a minimum password length (often 10 characters), and disable IP domain lookups.
Management Access: Configure a domain name (e.g., cisco.com), generate 1024-bit RSA keys, and enable SSH version 2 on VTY lines.
Brute-Force Protection: Use commands to block login attempts for a specified period (e.g., 1 minute) after 3 failures in 60 seconds. 3. Advanced Layer 2 and Layer 3 Features

Defining routes to internal networks and a default route to the ISP. Verification commands (e.g., show ip route show ip int brief show etherchannel summary ) to confirm connectivity.
The CCNA-2 v7.0 Case Study (Rev B) involves configuring a merged network for the "Carl I. Samson Company (C.I.S. Co)" following its acquisition of "Big-Corp". The network spans locations in Bangor, Phoenix, and Chicago and requires the implementation of dual-stack IPv4/IPv6 addressing, static routing, and Layer 2 security. 1. Design the Addressing Scheme If you tell me exactly what is written
You must use Variable Length Subnet Masking (VLSM) to design both IPv4 and IPv6 schemes.
IPv4: Subnet the provided LAN network into sizes that fit the specific host requirements for each branch (Bangor, Phoenix, Chicago).
IPv6: Implement a global unicast addressing scheme. Ensure every router interface and host is configured for dual-stacking (both versions running simultaneously). 2. Configure VLANs and Trunking
Organize the network into logical segments to manage broadcast domains and security.
VLAN Creation: Create and name VLANs on all switches as specified in the case study documentation.
Trunking: Configure ports connecting switches (and switches to routers for Router-on-a-Stick) as 802.1Q trunks.
Inter-VLAN Routing: On the Main Router or Multilayer Switch (MLS), configure sub-interfaces (for Router-on-a-Stick) or Switched Virtual Interfaces (SVIs) to allow communication between different VLANs. 3. Implement Layer 2 Security Secure the switch access layer against common attacks.
Switchport Security: Enable switchport port-security on access ports. Set a maximum number of MAC addresses (typically 1 or 2) and use violation restrict or shutdown.
Unused Ports: Disable all unused ports with the shutdown command and move them to a "Black Hole" VLAN (e.g., VLAN 999). 4. Configure DHCP and Wireless Enable automatic addressing and wireless connectivity.
DHCP Server: Configure R1 or a central server to provide IPv4/IPv6 leases. Use ip dhcp excluded-address to protect static IPs like gateways.
Wireless LAN (WLAN): Set up the Home Router and Access Points with specific SSIDs and WPA2 security. Ensure wireless clients can successfully obtain IP addresses from the DHCP server. 5. Establish Connectivity with Static Routes
Since this revision explicitly calls for static routing, you must manually define the paths between Bangor, Phoenix, and Chicago.
The CCNA-2 v7.0 Case Study (Rev B) acts as a capstone project for the Switching, Routing, and Wireless Essentials (SRWE) course, requiring the integration of VLANs, STP, security, and routing for the C.I.S. Co. expansion. The project necessitates configuring IPv4/IPv6, EtherChannel, and wireless LAN controllers, commonly documented in resources available on sites like Course Hero and Scribd.
