NET-330 Lab 5-1 – Community Healthcare Network

This repository documents the full Packet Tracer build and configuration for the Community Healthcare small enterprise network.

📡 Topology

The network follows a Single Distribution Area design:

  • 3560-24PS Hospital Router – Border / Distribution (MLS with inter-VLAN routing)
  • North Core and South Core 2960s – Core switches
  • Data Center Core 2960 – connects DHCP and DNS servers
  • North Edge and South Edge 2960s – Edge access switches
  • Server-PT DHCP – DHCP services
  • Server-PT DNS – DNS services
  • Test PCs on Clinic VLAN for validation

⚙️ Key Device Configurations

All switches and the 3560 were configured via CLI with the following highlights:

  • Enabled ip routing on the 3560
  • Created VLANs 10,20,30,40 and assigned SVI IPs
  • Configured trunk links between the 3560 and core/edge switches
  • Configured access ports per VLAN on edge switches
  • Added ip helper-address on the 3560 SVIs to forward DHCP requests

Full configuration blocks are stored in configs/ (not shown here).

✅ Lab Validation

  • Clients on each VLAN successfully received DHCP addresses.
  • Inter-VLAN routing functional.
  • DNS records resolved correctly from client PCs.

Notes & Troubleshooting

  • Ensured no shutdown on all SVI interfaces.
  • Used show interfaces trunk to confirm trunk VLANs.
  • Verified helper addresses for DHCP relay.

Mask: 255.255.255.0

Gateway: 10.10.0.1

DNS: 10.10.0.11

Services → DHCP → Service ON

Add Pools:

Clinic – Net 10.10.2.0/23 Gateway 10.10.2.1 DNS 10.10.0.11 Start 10.10.2.10

Visitor – Net 10.10.4.0/23 Gateway 10.10.4.1 DNS 10.10.0.11 Start 10.10.4.10

6️⃣ Client Configuration & Testing
Connect the Test Computer to NORTH_EDGE on an access port in VLAN 10.

Desktop → IP Configuration → DHCP to obtain an address.

In Command Prompt verify:

bash
Copy code
ipconfig
ping 10.10.2.1     # Clinic Gateway
ping 10.10.0.10    # DHCP Server
ping 10.10.0.11    # DNS Server
ping ns.lab.com    # DNS name resolution
ping dhcp.lab.com  # DNS name resolution
All pings should succeed.

7️⃣ Validation Commands on 3560
bash
Copy code
show ip interface brief      # All VLAN interfaces up/up with correct IPs
show interfaces trunk        # Verify allowed VLANs 1,10,20,30,40
8️⃣ Screenshots to Include in GitHub Repo
Upload each PNG to an images/ folder and reference them in your README:
