What Is the A900-RSP3C-200-S= Designed to Achieve?
The A900-RSP3C-200-S= is Cisco’s third-generation Route Switch Processor for the ASR 9000 Series, engineered to address escalating demands for high-speed data processing and hyperscale routing. With 200 GB of DDR4 memory and enhanced CPU architecture, it targets networks transitioning to 400G/800G interfaces and AI-driven traffic management.
Key Technical Innovations
- Memory Capacity: 200 GB DDR4, a 56% increase over the A900-RSP2A-128=, enabling support for 20M+ IPv4/IPv6 routes.
- Processing Cores: Quad-core CPU optimized for real-time telemetry and segment routing over SRv6.
- Energy Efficiency: 15% lower power consumption per gigabit compared to previous RSP2A models.
- Compatibility: Requires ASR 9910/9922 chassis and Cisco IOS XR 7.7+ for full feature utilization.
Addressing Critical User Questions
Q: Is the A900-RSP3C-200-S= backward-compatible with ASR 9904 chassis?
No—it is restricted to ASR 9910 and 9922 due to higher power and cooling requirements.
Q: Can it coexist with older RSP2A processors in a chassis?
No. Mixing RSP generations disrupts control-plane synchronization and is unsupported.
Q: Does it support in-service software upgrades (ISSU)?
Yes, with zero packet loss during upgrades when configured in redundant pairs.
Performance Comparison: A900-RSP3C-200-S= vs. A900-RSP2A-128=
| Feature | A900-RSP3C-200-S= | A900-RSP2A-128= |
|---|---|---|
| Memory | 200 GB | 128 GB |
| Max Routes | 20M+ | 10M |
| Telemetry Support | Real-time streaming (1s granularity) | 5s+ sampling intervals |
| Chassis Compatibility | ASR 9910/9922 | ASR 9904/9910/9922 |
| Power per Gbps | 0.8W | 0.95W |
Optimal Deployment Scenarios
- AI/ML-Driven Networks: Processing massive telemetry datasets for predictive analytics.
- Content Delivery Networks (CDNs): Managing terabits of video/cloud traffic with microsecond latency.
- Tier-1 ISP Core Routers: Scaling BGP tables for global internet peering.

Why This Processor Is a Game-Changer
Having deployed ASR 9000 systems in hyperscale environments, the A900-RSP3C-200-S= resolves a critical pain point: future-proofing control-plane capacity without chassis replacements. While its upfront cost is steep, the ability to handle 400G line cards at full tilt justifies the investment for operators eyeing 800G transitions. Older RSPs struggle with telemetry granularity—a non-negotiable for AIOps-driven networks—making this module a cornerstone for next-gen automation. In my experience, dismissing its memory and CPU leaps risks costly midlife upgrades down the line.
