: 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
: Configure ports connecting switches (and switches to routers for Router-on-a-Stick) as 802.1Q trunks .
To connect the corporate headquarters to an ISP or remote office, you must configure static routing or Single-Area OSPFv2. OSPFv2 Dynamic Routing Configuration
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.
Note: Making user-facing subinterfaces passive prevents unnecessary OSPF hello packets from saturating consumer segments and mitigates security risks. NAT (Network Address Translation) for Internet Access
For branch locations lacking high-end Layer 3 switches, sub-interfaces are provisioned on physical router links to bridge local VLANs. Each sub-interface handles 802.1Q tag encapsulation and maps to the appropriate native VLAN configuration:

Additional security measures required in Rev B include:
: Segregating traffic for security and performance using 802.1Q trunks.
[Access Port] ---> (Port Security: Max 2 MACs) ---> [Drop Unknown violation] [Trunk Port] ---> (802.1Q Native VLAN 99) ---> [Disable DTP Autonegotiation] Essential Switch Configurations
To successfully complete Revision B of this case study, network administrators and students must transition the disparate networks into a unified corporate infrastructure using standard Cisco IOS configurations. The implementation requires a deep understanding of dual-stack IPv4/IPv6 static routing, VLAN segmentation, switch security hardening, DHCP scopes, enterprise wireless networking, and Spanning-Tree Protocol optimization. Technical Requirements Matrix Deployment Phase Core Technologies Implemented Key Cisco IOS Configurations Expected Operational Outcomes
Prevent routing overhead and security leaks by disabling OSPF hellos on user-facing interfaces:
: 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.
A well-designed IP addressing scheme is the foundation of any network. In the ccna-2v7.0 case study -rev b- , students are often given a single network address (like a /23) that must be subnetted to accommodate multiple LANs and WAN point-to-point links. This is where becomes critical.
Network nodes are configured using a dual-stack model to allow concurrent traversal of IPv4 and IPv6 traffic.
Before advanced features are added, you must harden each network device: Initial Settings
Restrict access to the Management VLAN (VLAN 30). Only permit specific IT administrator hosts to access VTY lines via SSH. Step-by-Step Implementation Strategy
