5. Verification
Note on Versions:
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
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- is a comprehensive capstone project within the Cisco Networking Academy's Switching, Routing, and Wireless Essentials (SRWE) curriculum. It serves as a practical assessment where students must design, configure, and troubleshoot a multi-site enterprise network that reflects real-world deployment challenges. Objectives of the Case Study
The primary goal of Revision B is to validate your ability to integrate the core technologies introduced in CCNA v7.0. Key objectives include:
VLAN and Trunking Implementation: Segregating traffic for security and performance using 802.1Q trunks.
Redundancy Protocols: Configuring EtherChannel for link aggregation and Spanning Tree Protocol (STP) to prevent loops.
Dynamic Addressing: Setting up DHCPv4 and DHCPv6 (Stateless/Stateful) to automate IP management.
Routing and Security: Implementing Inter-VLAN routing (Router-on-a-Stick or Layer 3 Switching) and securing the infrastructure with SSH and Port Security. Core Configuration Components
The case study typically requires a hands-on approach using Cisco Packet Tracer or physical hardware to meet the following requirements: 1. Layer 2 Redundancy and Switching
Students must ensure high availability by configuring EtherChannel (LACP) between core switches. This allows for increased bandwidth and prevents a single point of failure. Additionally, the STP Bridge Priority must be adjusted to designate specific switches as Root Bridges for different VLANs. 2. Advanced IP Services ccna-2v7.0 case study -rev b-
A major focus of the Rev B version is DHCP Relay. When the DHCP server is located in a different subnet, students must configure the ip helper-address on the router interfaces to forward local broadcast requests. This ensures that clients in remote branches can still receive dynamic addressing. 3. WLAN Configuration
In line with modern enterprise needs, the study often includes the setup of a Wireless LAN Controller (WLC). This involves: Defining SSIDs with WPA2-PSK or Enterprise authentication. Mapping SSIDs to specific VLANs.
Ensuring seamless connectivity between wired and wireless clients. Troubleshooting and Best Practices
The -Rev B- designation often indicates updated security requirements or revised IP addressing schemes compared to the original version. To succeed, students should follow these Cisco-recommended practices:
Document the Topology: Always maintain an up-to-date IP address table.
Verify Step-by-Step: Use commands like show ip interface brief, show etherchannel summary, and show vlan brief after every major configuration block.
Secure Management: Always disable unused ports and use secret passwords rather than plain-text. Recommended Study Resources

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
, 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.
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. | Device | Interface | IP Address |
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.

It looks like you’re looking for a proper guide for the CCNA v7.0 (2.7.0) Case Study – Revision B.
First, a quick clarification:
The official Cisco NetAcad curriculum for CCNA 2 v7.0 (Switching, Routing, and Wireless Essentials) includes several Case Studies depending on the instructor or region — but the most common “Rev B” case study focuses on multi-switch configuration, VLANs, trunking, STP, EtherChannel, and inter-VLAN routing, often using Packet Tracer.
Below is a structured guide to complete the standard CCNA 2 v7.0 Revision B Case Study successfully.
Additional security measures required in Rev B include:
These steps adhere to the defense-in-depth principle, reducing the attack surface of the network.
One of the most time-consuming parts of the Rev B case study is configuring DHCP for all VLANs. The case study usually prohibits using a separate server; R1 or R2 must act as the DHCP server.
Since devices in different VLANs need to communicate (e.g., Management accessing a server in Operations), routing between VLANs is necessary. The case study implements a “Router-on-a-Stick” topology where the router’s single physical interface is divided into logical subinterfaces.
Configuration on the router involves:
Each subinterface serves as the default gateway for its respective VLAN. Verification includes show ip route and pinging between hosts on different VLANs.
