Because different VLANs reside on separate subnets, a Layer 3 device must route traffic between them. In Rev B, this is typically handled via a approach or Layer 3 multi-layer switches. Router-on-a-Stick Subinterface Blueprint
Revision B frequently provides a base network address block (such as 192.168.10.0/24 or a private Class B block like 172.16.0.0/16 ) and requires you to allocate subnets based on host counts. Sample VLSM Table Strategy
ip route 0.0.0.0 0.0.0.0 [next-hop-ip]
For routing between the switch block and the rest of the network (including a connection to a simulated ISP), the case study will require the configuration of a dynamic routing protocol, such as . OSPF is an open standard, link-state protocol, making it ideal for real-world networks. ccna-2v7.0 case study -rev b-
The is a cornerstone practical assignment in the Cisco Certified Network Associate (CCNA) curriculum. It tests a student's ability to design, configure, secure, and troubleshoot a medium-sized enterprise network using Cisco IOS commands.
Convert interfaces connecting to routers from Layer 2 to Layer 3 using no switchport .
Configure specific ports with maximum 25 MAC addresses, violation mode protect or restrict , and aging time 5 minutes .
The -Rev B- case study typically presents a multi-site enterprise topology that requires end-to-end connectivity, redundancy, and security. The architecture simulates a growing company that needs to modernize its infrastructure. 1. Multi-Tier Switching and VLANs The is a cornerstone practical assignment in the
: 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.
Acts as the central anchor point for corporate operations.
Pro-Tip: In both the case study and the actual certification exam, you will be heavily penalized if you forget to save your configurations. Always run copy running-config startup-config on every emulated device. 🚀 Modernizing the Network: Wireless & Automation
