The Case Study (Revision B) typically simulates a multi-department corporate headquarters or a university campus network that requires segmentation, high availability, dynamic routing, and robust security. Core Business Constraints

: Evaluates ACL parameters for ordering and filtering logic.

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. ccna-2v7.0 case study -rev b-

The acquisition requires explicit structural isolation between functional groups. The network uses custom Variable Length Subnet Masking (VLSM) and IPv6 Global Unicast Addresses (GUA) to provision the following segments:

The local edge router routes traffic between departments while acting as the default gateway for local subnets. The sub-interfaces must terminate IPv4 and IPv6 traffic simultaneously: [ PC Client ] ──(DHCP Discover)──► [ Router

VLANs must be provisioned and assigned uniform descriptive names across all local access switches.

Before dynamic routing protocols can be deployed, basic connectivity must be established. The initial configuration phase of the case study typically involves setting up to enable communication between directly connected routers.

Any unassigned switch port presents an open physical entry point into the corporate intranet. Secure these ports by moving them to the black-hole VLAN and shutting them down:

Securing management planes is the foundation of structural network safety. These configurations prevent brute-force attempts and mandate encrypted management tunnels. Baseline Device Configuration Script The port had instantly Error-Disabled Since devices in

: 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.
