Why Choose This Product?

• 40 Gbps-class aggregation capability - Provides substantial routing throughput for demanding WAN and edge aggregation requirements without immediately moving to a larger chassis. 
• Modular 8-SPA architecture - Lets infrastructure teams select appropriate interface adapters as connectivity requirements evolve, protecting the initial chassis investment. 
• Enterprise-grade ASR1000 platform - Places the router within Cisco’s established ASR 1000 family for organizations standardizing their routing infrastructure.
• Flexible control/data-plane architecture - Dedicated RP and ESP slots allow the platform to be engineered around routing and service-processing requirements. 
• 4RU footprint - Provides a useful balance between modular expansion and rack-space consumption for network rooms and data centers.
• Cisco ONE procurement model - C1-ASR1004/K9 provides a defined Cisco ONE hardware PID, while the applicable software suites can be configured according to the deployment requirement. 
• Software redundancy capability - Cisco specifies software redundancy without requiring redundant hardware, which can help control infrastructure complexity and capital expenditure. 
• Migration planning clarity - Because Cisco has published an EoL notice for the ASR1004, buyers can make an informed decision about replacement, support availability and migration strategy rather than treating lifecycle status as an unknown.
