If you don’t have instructor access, check your course syllabus or ask your instructor for “SRWE Case Study Rev B.”
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.
The CCNA-2v7.0 Case Study -Rev B- is not merely a test of rote commands; it is a simulation of a network engineer’s daily workflow. By methodically working through VLAN segmentation, inter-VLAN routing, DHCP, static routing, NAT, and ACLs, you are constructing a small enterprise network from scratch.
Remember the troubleshooting mindset: start at Layer 1, verify Layer 2, and only then proceed to Layer 3 and above. Use ping, traceroute, and show commands relentlessly. If a ping fails, check the ARP table, check the routing table, and verify ACLs.
Mastering this case study will leave you with a portfolio-worthy configuration and the confidence to move on to the third CCNA v7.0 course (ENSA) and, ultimately, the CCNA certification exam. Good luck, and happy configuring.
Next Steps: After completing Rev B, review your configuration against the official scoring rubric. If possible, have a peer review your ACL logic. Then, document every interface IP, VLAN mapping, and route in a network diagram – that documentation is a habit of successful professionals.
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
If you are currently working on this case study, here is a breakdown of the typical tasks involved in Rev B so you can verify your work:
1. Addressing Table Design
2. VLAN Configuration
3. Inter-VLAN Routing
4. Services (DHCP/SSH)
5. Verification
Note on Versions:
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
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 ccna-2v7.0 case study -rev b-
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

Are there specific Packet Tracer instructions or configuration commands from the Case Study -Rev B- you would like me to explain further?
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.

CCNA-2 v7.0 Case Study (Revision B) is a comprehensive capstone project within the Switching, Routing, and Wireless Essentials (SRWE)
course. This particular scenario typically revolves around the Carl I. Samson Company (C.I.S. Co)
, a firm based in Bangor, Maine, that has recently acquired a corporation with branch offices in Phoenix, AZ, and Chicago, IL.
The objective is to design, implement, and secure a multi-site network using a combination of IPv4 and IPv6
static routing until a permanent dynamic routing solution is decided. Core Phases of the Revision B Case Study
The project is generally divided into distinct phases that test your ability to build a functional and secure enterprise network. 1. IP Addressing and VLAN Design
You are tasked with creating a logical addressing scheme to support the different branches. VLAN Implementation
: Configuring multiple VLANs to segment traffic between departments (e.g., Management, Sales, Guest). Subnetting
: Applying IPv4 VLSM and IPv6 prefix assignments to maximize address efficiency. Inter-VLAN Routing Router-on-a-Stick
or Layer 3 switch configurations to enable communication between these segments. 2. Basic Device Configuration & Security
Before advanced features are added, you must harden each network device: Initial Settings
: Setting hostnames, encrypting all plain-text passwords, and configuring a "Banner Motd" to warn unauthorized users. SSH Access : Disabling insecure Telnet and configuring SSH Version 2 with a local username (e.g., ) and a 1024-bit RSA key for remote management. Login Security
: Implementing "block-for" commands to prevent brute-force attacks (e.g., disabling login for 1 minute after 3 failed attempts within 60 seconds). 3. Advanced Switching and Routing
This phase focuses on redundancy and reaching remote networks:
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.
Usually requires:
A small company, Clearview Media, has acquired a second office. You are assigned as the network engineer to design, implement, and verify the new branch network and ensure connectivity to the corporate headquarters via a serial WAN link. The network must support three departments (Sales, Engineering, and HR), provide secure access to printers and servers, and allow remote administration from headquarters. The network should be segmented using VLANs, use inter-VLAN routing on a router-on-a-stick, implement OSPF for dynamic routing with HQ, provide NAT for Internet access, secure management via SSH and access lists, and supply DHCP for hosts.
