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 ccna-2v7.0 case study -rev b-
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:
The CCNA-2v7.0 Case Study (Rev B), often associated with Packet Tracer activity 14.6.1, is a comprehensive, hands-on lab designed to test practical application of CCNA 2 (Switching, Routing, and Wireless Essentials - SRWE) concepts . It requires learners to implement a secure, multi-site network for the "Carl I. Samson Company" (C.I.S. Co), involving Phoenix, Chicago, and Bangor locations . Core Components & Objectives
Topology: Involves complex routing between multiple geographical locations (Bangor, Chicago, Phoenix) . IP Addressing: Subnetting the 10.10.64.0/21 range .
VLANs & Trunking: Setting up VLANs, Access Ports, and Trunk Ports .
Static Routing: Implementing IPv4 and IPv6 static routes, including potential floating static routes .
Switch Security: Configuring DHCP Snooping, Port Security, and Dynamic ARP Inspection (DAI) .
Wireless: Configuring a Wireless LAN Controller (WLC) and Access Points .
Spanning Tree Protocol (STP): Configuring and optimizing STP for redundancy . Detailed Review CCNA-1 Case-Study-7.0 -.docx - Course Hero
The first section of the case study focuses on Layer 2 readiness. Misconfiguring VLANs here will cascade into routing and security failures later.
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:
This assumes a typical scenario where you are given a network topology with multiple routers, switches, VLANs, static/dynamic routing, ACLs, NAT, and DHCP.
Adjust the IP addressing and device names to match your specific case study details.
[PC1] --(VLAN10)-- SW1 ----(EtherChannel)---- SW2 ----(trunk)---- Router
[PC2] --(VLAN20)-- SW1 |
SW3 (VLAN10/20)
If you tell me exactly what is written in your case study packet (the IP scheme, VLAN numbers, number of switches), I can give you a ready-to-use configuration script for Rev B.
All required objectives were met:
✅ VLANs configured and trunking operational
✅ Inter-VLAN routing verified
✅ OSPF and static routes functional
✅ DHCP providing IPs to end devices
✅ NAT overload working for internet-bound traffic
✅ SSH secured with ACL
The network operates as per the case study requirements of Revision B.
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.
