Note: IP addresses are intentionally anonymized. This project represents a simulated lab environment.
Overview
Designed and implemented a routed enterprise lab network by standardizing Cisco IOS images, configuring a terminal server and TFTP backups, segmenting VLANs, and deploying RIP with NAT and traffic analysis via Wireshark.

Implementation highlights
- Routing design choices (areas/AS, adjacency requirements)
- Layer 2/3 boundaries and VLAN strategy
- Access control approach (ACLs/filters) and validation method
- Redundancy strategy and failover behavior
- Routing Protocol interoperability
- IPv6 transition strategy
Commands / config snippets (IPs anonymized)
# Example snippet
show ipv6 int brief
show ipv6 ospf neighbor
show ipv6 route
show access-lists
Verification
- Connectivity tests (ping6, traceroute)
- OSPF neighbor/LSA checks
- ACL behavior verification (allowed vs blocked traffic)
