ASR1004 vs. ASR1006: Which Cisco Router Meets Your Enterprise Needs?

When upgrading your network infrastructure, Cisco’s ASR1004 and ASR1006 routers offer distinct advantages. This guide breaks down their differences to help you choose wisely.

1. Performance Breakdown

• ASR1004:

• Processor: Dual-core 1.2 GHz CPU

• Memory: 4 GB RAM (expandable to 8 GB)

• Throughput: Up to 2 Gbps

• Latency: ~1.2 ms (ideal for branch offices)
  Best for small-scale routing with minimal latency sensitivity.

• ASR1006:

• Processor: Quad-core 1.8 GHz CPU

• Memory: 8 GB RAM (scalable to 16 GB)

• Throughput: Up to 10 Gbps

• Latency: ~800 μs (optimized for high-speed networks)
  Future-proof for demanding workloads like SD-WAN and VoIP.

Key Difference: The ASR1006 delivers 5x higher throughput and twice the memory, ensuring smoother performance under heavy traffic.

2. Core Features

The ASR1006 prioritizes scalability and security, while the ASR1004 focuses on cost-effective routing for smaller networks.

3. Design & Port Density

• ASR1004:

• Form Factor: 1 RU (compact)

• Expansion Slots: 2x (supports WIC/VIC modules)

• Cooling: Single fan tray.

• ASR1006:

• Form Factor: 1 RU (modular)

• Expansion Slots: 4x (accommodates security, WAN acceleration, or additional interfaces).

• Cooling: Redundant fan trays for 24/7 operation.

The ASR1006’s modular design future-proofs your network, while the ASR1004’s compact size saves rack space.

4. User Experience

• Configuration: Both support Cisco DNA Center and CLI, but the ASR1006 introduces zero-touch provisioning (ZTP) for large-scale deployments.

• Management: ASR1006 offers detailed analytics via NetFlow and telemetry, whereas ASR1004 relies on basic monitoring.

• Troubleshooting: ASR1006’s advanced logging simplifies issue resolution for complex networks.

Users value the ASR1006’s scalability but appreciate the ASR1004’s simplicity for edge deployments.

5. Pricing Structure

• ASR1004: ~2,500–4,000 (street price)

• ASR1006: ~10,000–15,000 (street price)

The ASR1006 commands a premium for advanced features, while the ASR1004 provides budget-friendly routing for smaller budgets.

6. Power Consumption

• ASR1004: ~120W (optimized for energy efficiency).

• ASR1006: ~250W (higher power draw reflects its enhanced capabilities).

Choose the ASR1004 for greener deployments, but accept the ASR1006’s power needs for performance.

7. Compatibility & Scalability

• ASR1004:

• Limited to basic WAN/LAN modules (e.g., Cisco HWIC).

• Best paired with standalone security appliances.

• ASR1006:

• Supports 4G LTE, SFP+, and security modules (e.g., Cisco WSA).

• Integrates with Cisco DNA Center for automation.

The ASR1006’s flexibility ensures long-term relevance, while the ASR1004 suits static environments.

8. Software Support

• Both run IOS-XE, but the ASR1006 qualifies for advanced features like SD-WAN and 5G-ready firmware updates.

• The ASR1004 receives standard security patches but lacks cutting-edge enhancements.

9. English Summary

For non-Chinese readers:
The ASR1006 is a scalable, secure router for enterprises adopting SD-WAN and cloud-native apps. The ASR1004 is a budget-friendly, compact solution for branch offices with basic routing needs.

Final Verdict

Opt for the ASR1006 if you prioritize scalability, advanced security, and future-proofing. Choose the ASR1004 for cost-effective, plug-and-play routing in small-scale environments. Remember: Investing in the right router today prevents costly upgrades tomorrow.
