Azure Virtual Network Skill
This skill provides expert guidance for Azure Virtual Network. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, and configuration. It combines local quick-reference content with remote documentation fetching capabilities.
How to Use This Skill
IMPORTANT for Agent: This file may be large. Use the Category Index below to locate relevant sections, then use
read_filewith specific line ranges (e.g.,L136-L144) to read the sections needed for the user's question
IMPORTANT for Agent: If
metadata.generated_atis more than 3 months old, suggest the user pull the latest version from the repository. Ifmcp_microsoftdocstools are not available, suggest the user install it: Installation Guide
This skill requires network access to fetch documentation content:
-
Preferred: Use
mcp_microsoftdocs:microsoft_docs_fetchwith query stringfrom=learn-agent-skill. Returns Markdown. -
Fallback: Use
fetch_webpagewith query stringfrom=learn-agent-skill&accept=text/markdown. Returns Markdown.

| Troubleshooting | L35-L43 | Diagnosing and fixing Azure VM/VNet connectivity issues: routing and NSG problems, NVAs and routing appliances, SMTP blocking, VNet peering, encryption, and VNet deletion errors. |
| Best Practices | L44-L55 | Network performance and connectivity guidance: VNet design, NSGs, service endpoints, outbound access, MTU/TCP tuning, and tools to test throughput and latency on Azure VMs. |
| Decision Making | L56-L65 | Guidance on design choices: when to use accelerated networking, routing preferences, VNets vs appliances, IP upgrade paths, VNet integration options, and cost/performance trade-offs. |
| Architecture & Design Patterns | L66-L75 | Designing VNet architectures: subnet extension for migrations, VNet peering, hybrid two-tier apps, traffic mirroring with TAP, topology planning, and custom routing options. |
| Limits & Quotas | L76-L82 | VM networking limits: MANA support per VM size, static public IP assignment and quotas, and VM network throughput caps and how they affect performance. |
| Security | L83-L91 | Securing virtual networks with policies and encryption, including Kubernetes network policies, Azure Policy for VNets, VNet encryption, and restricting storage egress via service endpoint policies. |
| Configuration | L92-L120 | Configuring Azure Virtual Network components: DNS, IPs (public/private, prefixes, IPv4/IPv6), NAT/load balancer/firewall/VPN, subnet delegation, monitoring, NSG logs, and DHCP-related setups. |
