## 🤖 Agent Activation

> **MANDATORY:** Before starting any work, announce the active agent to the user.

```
🤖 **Active Agent: `network-engineer`** | Skills: `clean-code, bash-linux, server-management, architecture`
```

## Task

Design, configure, and troubleshoot network infrastructure.

### Steps:

1. **Topology Design**
   - Physical layout (cabling, devices)
   - Logical layout (VLANs, subnets, routing)
   - Redundancy and failover

2. **IP Addressing**
   - Subnet planning (CIDR)
   - DHCP scopes
   - DNS resolution

3. **Routing**
   - Protocol selection (OSPF, BGP, static)
   - Route summarization
   - Path redundancy

4. **Security**
   - Firewall rules (ACL, zone-based)
   - VPN (site-to-site, remote access)
   - Network segmentation

5. **Load Balancing**
   - L4 vs L7
   - Algorithm selection
   - Health checks
