Cisco ASR 1004 Router

The Cisco ASR 1004 Router in a 4-rack unit (RU) form factor supports up to 8 shared port adapters (SPAs) and comes with one route processor and one embedded services processor slot. This provides flexibility for future upgrades, enhancing control plane and data plane scalability.

  • High-performing edge solution for the private WAN
  • WAN aggregation or Internet gateway device
  • As a broadband Layer 2 Tunneling Protocol (L2TP) access concentrator (LAC) or L2TP Network Server (LNS)

Running on Cisco IOS XE Software, the Cisco ASR 1004 router supports software redundancy and in-service software upgrades (ISSU) without redundant hardware.

Cisco ASR 1004 Router Features

The Cisco ASR 1000 Series Routers carry a modular yet integrated design, so network operators can increase their network capacity and services without a hardware upgrade. With flexibility in the number of connections, speed maximums, and price, you don’t have to under-provision or overprovision for any network location. Alternatively, you also have the option to buy an “-X” model, so you can increase throughput by simply purchasing upgrade licenses as you grow to increase your network speed dynamically.

Cisco ASR 1004 Router Technical Specifications

Feature Specification
Redundant hardware
components and power
Provides system and business continuity.
Redundant Route Processors and Embedded Services Processors in ASR 1006 and ASR 1013.
Redundant instances of Cisco IOS XE Software in ASR 1001, ASR 1001-X, ASR 1002, ASR 1002-X, and
Stateful intrachassis
Redundant hardware combined with modular software contains faults preventing systemwide failure.

99.999% (“five-nines”) availability for consistent, high-performance user application experiences.
In-Service Software Upgrade
(ISSU) support
No need to schedule downtime windows; changes are made while the system keeps on working, with nonstop
routing availability.
Cisco IOS XE Software Subpackage
Ability to upgrade individual software components with reduced upgrade time.
Cisco QuantumFlow
Processor-based platform
Enables advanced services to operate at high speeds without the need for additional hardware or blades.
Hardware acceleration Features like QoS, crypto, and access control lists (ACLs) are processed in hardware
Control and forwarding-plane
Ability to scale control plane and data plane independent of each other.
Software modularity Allows you to mix and match the services that best meet your business needs; no “wasted” investments on
capabilities you don’t need.
Pay-as-you-grow licensing with
“-X” models
When you need greater throughput, you simply activate it with a change in software license, rather than
having to expend capital for additional hardware.
Cisco Shared Port Adapters
Allow you to reuse your investment in network I/O across platforms.
Cisco Network Interface
Modules (NIMs)
Allow you to reuse your investment in network I/O across platforms.
