What Is the ASR907-RSP3-BUN?
The ASR907-RSP3-BUN is a Cisco-certified hardware and software bundle designed for the ASR 900 Series routers, combining the Route Switch Processor 3 (RSP3) with essential licenses to unlock advanced routing, security, and automation features. This all-in-one package streamlines upgrades for service providers and enterprises modernizing edge or aggregation networks.
Core Technical Advancements
- Dual 2.4 GHz multicore CPUs: Delivers 80 Gbps throughput, doubling the performance of previous RSP2 modules.
- Integrated MACsec encryption: Supports hardware-accelerated 256-bit encryption for every port without external modules.
- Pre-installed licenses: Includes Cisco IOS XR Software 7.5.1 with essentials like Segment Routing, BGP-LU, and NetFlow.
ASR907-RSP3-BUN vs RSP2: Performance and Capability Comparison
| Factor | ASR907-RSP3-BUN | Legacy RSP2 Modules |
|---|---|---|
| Throughput | 80 Gbps | 40 Gbps |
| Encryption Support | Onboard MACsec (line rate) | Requires external crypto cards |
| Power Draw | 75W (30% less than RSP2) | 110W |
Addressing Critical User Concerns
Q: Does this bundle require a full chassis replacement?
No. The RSP3-BUN is hot-swappable, allowing in-service upgrades without network downtime.
Q: Can it coexist with older RSP modules in the same chassis?
Yes, but only in redundant configurations. Mixed generations require Cisco IOS XR 7.3.2+ for compatibility.
Q: How does it handle scalability for 5G fronthaul/backhaul?
The RSP3-BUN supports deterministic latency (<10µs) and 10,000+ SRv6 SIDs, making it ideal for 5G transport slicing.
Why This Bundle Simplifies Network Modernization
- Cost efficiency: Bundling licenses with hardware avoids 40-60% premium vs piecemeal procurement.
- Zero-touch provisioning (ZTP): Pre-configured licenses accelerate deployment for distributed sites.
- Future readiness: Prepares networks for 800G interfaces via software updates, avoiding hardware swaps.

Hands-On Experience
During a carrier’s 5G core rollout, the RSP3-BUN eliminated three major pain points: encryption bottlenecks, manual license allocation, and power constraints. While competitors chased niche features, this bundle’s holistic design proved that simplicity and raw performance aren’t mutually exclusive. For teams juggling CapEx and 24/7 uptime demands, skipping this upgrade isn’t an oversight—it’s a risk.
