Curious what the lab looks like?

As someone just starting out in the networking field, I’m excited to share that I’ve completed one of my most advanced hands-on labs using Cisco CML — and it’s working exactly as intended! 👏 This project demonstrates real-world skills with HSRP, VLANs, EtherChannel, NAT, ACLs, and more.
📌 Project Highlights
- 🧩 Set up HSRP with 2 ISPs (Airtel & BSNL) for gateway redundancy
- 🎛️ Created 4 VLANs across two Layer 2 switches, connected with EtherChannel
- 🔄 Configured DHCP on routers to dynamically assign IPs to VLANs
- 🛡️ Applied NAT with ACLs — allowing only VLAN 10 & 20 to access the internet
- 🚫 VLAN 30 & 40 are successfully blocked via ACL — verified through NAT debug and access-list logs
- ✔️ Verified internet access using ping 8.8.8.8 and checked NAT translations with
show ip nat translations
🛠️ Tools & Learning
- Cisco CML
- Alpine Linux (PCs)
- NAT, ACL, DHCP, HSRP, Inter-VLAN Routing
- Commands like
debug ip nat,show access-lists,show ip dhcp binding, etc. - Still a beginner, not started CCNP yet — learning every day through labs like this!
🎥 Soon, I’ll be uploading:
- GitHub repo with the full config files (coming soon)
- YouTube walkthrough with setup and explanation (video in progress)
