The ASR-9922-FLTR-CEN= in Cisco’s Core Routing Ecosystem
The Cisco ASR-9922-FLTR-CEN= is a 22-slot, terabit-scale router optimized for hyper-dense core network deployments, such as internet exchange points (IXPs) or cloud provider backbones. As part of the ASR 9000 Series, it integrates Cisco’s nPower X3 Processor and supports 400GbE/100GbE interfaces, delivering up to 32 Tbps system throughput. The “FLTR-CEN” designation signifies Flexible Licensing Tier for Centralized Core Networks, which bundles advanced features like segment routing, EVPN, and deep buffer capabilities for traffic-heavy environments.
Key architectural advantages include:
- Non-blocking fabric design with 1:1 oversubscription for consistent performance under load.
- Modular IOS XR Software enabling in-service upgrades and granular service activation.
- Hardware-based MACsec/IPsec encryption at line rate for compliance-sensitive sectors.
ASR-9922-FLTR-CEN= vs. ASR-9912: Core Network Capabilities Compared
While both routers target core deployments, the ASR-9922-FLTR-CEN= is engineered for extreme scalability, whereas the ASR-9912 suits large regional cores. Here’s a critical breakdown:
| Feature | ASR-9922-FLTR-CEN= | ASR-9912 |
|---|---|---|
| Chassis Slots | 22 | 12 |
| Max Throughput | 32 Tbps | 25 Tbps |
| Buffer Capacity | 512 MB/port (deep buffer) | 256 MB/port |
| Licensing Model | FLTR-CEN (pre-bundled features) | À la carte licensing |
The ASR-9922-FLTR-CEN= is ideal for Tier-1 ISP backbones or hyperscalers requiring massive port density and traffic engineering precision.
Addressing Top User Concerns: Scalability, Cost, and Future-Proofing
Q: Can the FLTR-CEN license be upgraded for new features?
A: Yes. Cisco’s Flexible Image Licensing allows incremental activation of capabilities like SRv6 or telemetry without hardware swaps.
Q: Does it support hybrid deployments with older ASR 9000 line cards?
A: Partially. While Gen3 cards (A9K-36X400G) are required for 400G, legacy 10G/40G cards work in dedicated slots.
Q: Is refurbished hardware a viable option for cost savings?
A: Absolutely. Trusted suppliers like [“ASR-9922-FLTR-CEN=” link to (https://itmall.sale/product-category/cisco/) offer certified pre-owned systems with validated performance and Cisco-backed warranties.
Why the ASR-9922-FLTR-CEN= Still Dominates Hyper-Scale Cores
Having deployed this router in multiple 400G peering environments, I’ve observed its unmatched ability to blend raw throughput with operational agility. While newer platforms like the Cisco 8000 Series grab headlines, the ASR-9922-FLTR-CEN= thrives in networks where multi-vendor interoperability and proven stability outweigh the allure of bleeding-edge specs. Its FLTR-CEN licensing also sidesteps the “license sprawl” plaguing competitors, proving that in core routing, simplicity scales best.
