Network Architecture Overview
Designed a secure dual-stack (IPv4/IPv6) enterprise network featuring VLAN segmentation, OSPF dynamic routing, and HSRP redundancy. Implemented EtherChannel (PAgP/LACP) for link aggregation and comprehensive security measures including ACL, port security, and DHCP snooping.
Key Implementations
-
Designed secure dual-stack network architecture using IPv4/IPv6 with VLAN segmentation and OSPF routing
-
Configured HSRP for gateway redundancy and EtherChannel (PAgP/LACP) for bandwidth aggregation
-
Implemented network services including DHCP, DNS, NAT, and monitoring via SNMP/Syslog
-
Secured infrastructure with ACLs, port security, DHCP snooping, and DAI
-
Configured enterprise WLAN with WLC and LWAP for wireless access

Project Description
This CCNA-level capstone project involved designing and implementing a comprehensive enterprise network infrastructure from the ground up. The design incorporates modern networking best practices including dual-stack (IPv4/IPv6) support, VLAN segmentation for traffic isolation, and dynamic routing with OSPF for efficient path selection.
The network features robust redundancy through HSRP for gateway failover and EtherChannel for link aggregation. Security was implemented at multiple layers including port security, DHCP snooping, Dynamic ARP Inspection (DAI), and access control lists. Wireless access was integrated via Cisco Wireless LAN Controller (WLC) and Lightweight Access Points (LWAP) with appropriate security measures.
The project demonstrates mastery of CCNA-level networking concepts including IP addressing schemes, VLAN trunking, inter-VLAN routing, dynamic routing protocols, network services (DHCP, DNS, NAT), and comprehensive network security implementations.
