As enterprise WAN traffic surges with cloud adoption, video collaboration, and mobility, your edge router must deliver consistent, high-performance forwarding without overprovisioning. The Cisco ASR1001-X is a compact 1RU aggregation services router built on the proven Cisco ASR 1000 Series architecture, purpose-designed for WAN edge, aggregation, and managed service provider deployments.
The ASR1001-X ships with a default forwarding capacity of 2.5 Gbps and can be incrementally upgraded to 5, 10, or 20 Gbps through simple software-activated performance licenses — protecting your investment as bandwidth demands grow. Its integrated route processor, embedded services processor (ESP), and SPA interface processor (SIP10) eliminate the need for separate blades, while six built-in 1GE SFP ports and two 10GE SFP+ ports provide flexible connectivity for diverse WAN and LAN topologies.
Running Cisco IOS XE, the ASR1001-X supports a comprehensive suite of enterprise routing protocols (BGP, OSPF, EIGRP, IS-IS), MPLS, and advanced services including NAT, Zone-Based Firewall, deep packet inspection, and up to 8 Gbps of hardware-accelerated crypto throughput via the Cisco QuantumFlow Processor. Dual hot-swappable AC power supplies deliver 1+1 redundancy, and the included 8 GB DRAM ensures headroom for large routing tables and concurrent service sessions. Whether you're consolidating branch WAN links, deploying L3VPN services, or migrating from legacy Cisco 7200 Series routers, the ASR1001-X delivers enterprise-grade performance, security, and scalability in a space-efficient package.
Features & Benefits
Pay-As-You-Grow Throughput
The ASR1001-X starts at 2.5 Gbps forwarding capacity and scales to 5, 10, or 20 Gbps with a simple software license upgrade. This eliminates costly hardware replacements and lets you align network investment with actual traffic growth — paying only for the capacity you need today while preserving a clear upgrade path.
Integrated Hardware-Based Security
A dedicated security processor delivers up to 8 Gbps of crypto throughput, accelerating IPsec VPN, DMVPN, and GETVPN services without impacting forwarding performance. Combined with Cisco Zone-Based Firewall and NAT, the ASR1001-X consolidates routing and security into a single platform — reducing the need for standalone security appliances.
Compact 1RU Design with Integrated Components
The route processor, embedded services processor, and SPA interface processor are all integrated into the 1RU chassis. This fixed architecture simplifies deployment, reduces cabling complexity, and conserves valuable rack space in enterprise data centers and service provider POPs.
Dual Hot-Swappable Power Supplies
The ASR1001-X includes two AC power supplies in a 1+1 redundant configuration. Hot-swappable design allows field replacement without service interruption, ensuring the high availability that business-critical WAN links demand.
Cisco IOS XE with Advanced Routing
Cisco IOS XE provides a modular, resilient operating system supporting BGP, OSPF, EIGRP, IS-IS, MPLS, and advanced traffic engineering. QuantumFlow Processor technology accelerates services like NAT, deep packet inspection (NBAR/AVC), and Cisco Unified Border Element (CUBE) — all in software, without additional hardware modules.
Flexible Interface Options
Six built-in 1GE SFP ports and two 10GE SFP+ ports provide high-density connectivity for WAN aggregation. An additional SPA bay supports legacy interface modules (T1/E1, T3/E3, serial) for mixed-media environments, making the ASR1001-X a versatile platform for diverse network topologies.
Deployment Scenarios
Enterprise WAN Edge & Aggregation
Deploy the ASR1001-X at the enterprise WAN edge to aggregate multiple branch connections, apply QoS policies, and enforce security. Scalable throughput licenses let you start small and grow capacity as traffic demands increase, without replacing hardware.
Managed Service Provider Edge
Service providers can use the ASR1001-X in points of presence (POPs) to deliver L3VPN, MPLS, and managed security services to business customers. The compact 1RU form factor and dual power supplies maximize density and uptime in colocation environments.
Cisco 7200 Series Migration
Organizations running end-of-life Cisco 7200 Series routers can migrate to the ASR1001-X for significantly greater forwarding performance, modern IOS XE features, and continued Cisco TAC support — all within the same familiar ASR 1000 architecture.
Data Center Interconnect (DCI)
Leverage the ASR1001-X's hardware-accelerated crypto and high-throughput forwarding to establish secure, high-performance interconnects between data center sites using DMVPN, GETVPN, or IPsec tunnels.
