Ccna-2v7.0 Case Study -rev B- Today

: Verifies that default gateways, summary routes, and directly connected subnets are actively registered.

core. But there were complications. The Dean insisted on total isolation for the research data, while the Student Union needed open Wi-Fi that wouldn't bog down the registrar’s office. Alex looked at the topology. It was a classic "Rev B" mess: VLANs 10, 20, and 99 were already saturated. The new wing required DHCP relay because the central server was three hops away. Inter-VLAN routing had to be handled by a new Layer 3 switch , replacing the aging "Router-on-a-Stick" setup. 2. The Implementation: Trunking and Tensions

To bind Bangor, Phoenix, and Chicago together without a dynamic protocol, explicit directional paths and fallback routes must be hardcoded. ccna-2v7.0 case study -rev b-

Assign access ports to the correct VLAN. For example, PC-A (Employee) goes into VLAN 10. Use switchport mode access and switchport access vlan 10 . Do not leave any port in the default VLAN 1 unless explicitly required.

: Configuring static and dynamic NAT, along with PAT (Port Address Translation), to allow private internal hosts to access the public internet. : Verifies that default gateways, summary routes, and

A design is only as good as its verification parameters. Use these core Cisco IOS commands to check deployment success:

For academic and simulation purposes, students can test and cross-verify these setup topologies directly inside Cisco Packet Tracer environments. You can download lab materials, interactive software, and additional reference modules directly through the Cisco Networking Academy platform. The Dean insisted on total isolation for the

The foundational step involves mapping out the VLAN topologies across the respective corporate offices and subnets. The Phoenix branch typically demands multi-department segmentation alongside a wireless management space. VLAN Mapping Example : Management & Operations VLAN 20 : Corporate Users

show spanning-tree vlan [vlan_id] : To confirm your root bridge election and port states.

show ip route : To inspect the routing table and ensure all subnets are learned dynamically or statically.
