About the Cisco ASR 1000 ASR1004 Cisco ASR 1000 / 5000 series router
The Cisco ASR1004 delivers modular, high-performance routing in a compact 4U rack-mount chassis, supporting dual redundant Route Processors and Embedded Services Processors that scale system throughput from 5 Gbps up to 40 Gbps depending on the installed ESP module. This architecture enables network engineers and IT infrastructure teams to match capacity to current demand while preserving upgrade paths for future growth without chassis replacement.
Built on Cisco's QuantumFlow Processor ASIC forwarding architecture, the ASR1004 combines unified data plane efficiency with comprehensive routing protocol support including BGP, OSPF, OSPFv3, IS-IS, EIGRP, and RIP variants. The platform runs Cisco IOS XE and integrates advanced features such as stateful NAT44/NAT64, hardware-accelerated IPsec with IKEv1/IKEv2, MPLS forwarding with L3VPN and L2VPN capabilities, Traffic Engineering via RSVP-TE, and Zone-Based Firewall protection. High availability is built in through redundant processor slots, Stateful Switchover, In-Service Software Upgrade, and Non-Stop Forwarding, minimizing unplanned downtime in mission-critical networks. Dual hot-swappable AC or DC power supplies and front-to-back cooling with hot-swappable fan trays ensure operational resilience across demanding environments operating between 0°C and 40°C.
