building realistic enterprise-style network topologies

I’ve been focusing on building realistic enterprise-style network topologies to strengthen my practical networking skills. This lab focuses on dual-stack networking (IPv4 & IPv6), network segmentation, and automated IP address management.

?️ What I implemented in this project:

? Inter-VLAN Routing

Configured communication between multiple VLANs using both Router-on-a-Stick and Layer 3 Multilayer Switch (SVIs) to simulate real enterprise routing scenarios.

? Advanced DHCP Configuration

Implemented DHCPv4 and DHCPv6 to dynamically assign IP addresses to hosts, reducing manual configuration and improving scalability.

? IPv6 Network Deployment

Configured SLAAC (Stateless Address Autoconfiguration) along with Stateful and Stateless DHCPv6, including proper use of M-Flag and O-Flag for address and configuration control.

? DHCP Relay (ip helper-address)

Configured relay agents to allow a centralized DHCP server to provide IP addresses across multiple networks and VLANs.

? Network Verification

Performed connectivity testing using ICMP to verify successful communication across the entire dual-stack IPv4/IPv6 topology.
