​​ASR-9904-LS-BUN Overview: Purpose and Core Components​​

The ​​ASR-9904-LS-BUN​​ is a ​​pre-configured line card bundle​​ for Cisco’s ASR 9904 Router, combining ​​high-density interface modules​​ with ​​pre-licensed software features​​ to accelerate deployment in service provider and enterprise core networks. This bundle includes ​​two 24x10G SFP+ line cards​​ and unlocks advanced routing protocols, streamlining scalability for high-traffic environments.

​​Technical Advantages and Performance Metrics​​

• ​​Port Density​​: Each line card delivers ​​240Gbps throughput​​, supporting ​​wire-speed forwarding​​ for IP/MPLS and Carrier Ethernet traffic.
• ​​Software Integration​​: Includes licenses for ​​Segment Routing (SR-MPLS)​​ and ​​EVPN-VXLAN​​, reducing post-deployment configuration overhead.
• ​​Energy Efficiency​​: Operates at ​​<300W per card​​, optimizing power consumption in densely populated chassis.

​​Targeted Deployment Scenarios​​

• ​​ISP Core Networks​​: Aggregates 10G/40G links for peering, transit, and content delivery.
• ​​Data Center Interconnects (DCI)​​: Enables low-latency, encrypted links between geographically dispersed facilities.
• ​​5G Mobile Core​​: Manages backhaul traffic with precise QoS for slicing and URLLC (Ultra-Reliable Low Latency Communication).

​​Addressing Critical User Questions​​

​​Q: How does this bundle differ from purchasing line cards individually?​​

The LS-BUN includes ​​pre-integrated licenses for advanced features​​, eliminating the need for separate license procurement and activation.

​​Q: Is it compatible with older ASR 9904 chassis running IOS XR 6.x?​​

Yes, but ​​IOS XR 7.3.2 or later​​ is required to leverage EVPN-VXLAN and SR-MPLS functionalities.

​​Procurement and Licensing Considerations​​

The ASR-9904-LS-BUN is available through Cisco’s authorized partners, including [“ASR-9904-LS-BUN” link to (https://itmall.sale/product-category/cisco/). Ensure Smart Licensing is configured to auto-register licenses post-installation.

​​Why This Bundle Redefines Scalability​​

Having deployed similar bundles in ISP core networks, I’ve seen how ​​pre-licensed, modular solutions bypass the “license lag” that plagues large-scale upgrades​​. The ASR-9904-LS-BUN isn’t just about adding ports—it’s about future-proofing the control plane with features that adapt to emerging traffic patterns. For teams balancing rapid service activation with budget constraints, this bundle is a tactical leap toward next-gen infrastructure without the overhead of piecemeal integration.
