Cisco ASR 1000 Series
the release notes. The (optionally) hardware-redundant route processor and ESP
configuration in the Cisco ASR 1006 Router does not support Cisco IOS Software
redundancy in a single route processor since each of the two RPs support one Cisco
IOS XE image.
Benefits and Advantages
Three Models
The Cisco ASR 1000 Series consists of three
different versions: the Cisco ASR 1002 Router,
the Cisco ASR 1004 Router, and the Cisco ASR
1006 Router .
Fills a Gap
From a price-to-performance perspective, the Cisco
ASR 1000 Series Routers solution fits well between
the Cisco 7200 Series Routers and the higher-end
Cisco 7600 Series Routers and Cisco Catalyst ®
6500 Series Switches, thus dramatically enhancing
the Cisco midrange routing portfolio .
Enhanced Value
The Cisco ASR 1000 Series provides a significant
enhanced value compared to prior generations
of Cisco midrange routing solutions by providing
more than tenfold performance improvement with
services running . Additionally, the routers have
hardware and software redundancy, as well as an
industry-leading high-availability design .

Multiple Services
The Cisco ASR 1000 Series delivers multiple
services embedded in the Cisco QuantumFlow
Processor at wire speeds of up to 20 Gbps .
The services supported on the Cisco QuantumFlow
Processor include:
• Security services, such as encryption and firewall
• Quality of service (QoS)
• Network Based Application Recognition (NBAR)
• Cisco IOS ® Flexible Packet Matching
• Broadband aggregation
• Session border controller, among others
Software and Hardware Redundancy
With the separation of the control and data planes
in the Cisco ASR 1000 Series Routers architecture,
software redundancy (on the Cisco ASR 1002 and
1004 Routers) and hardware redundancy (on the
Cisco ASR 1006 Router) are provided .
Nonstop Communications
Additionally, the modular Cisco IOS XE Software
that is introduced with the Cisco ASR 1000 Series
facilitates in-service software upgrade (ISSU)
When to Deploy
Deploy the Cisco ASR 1000 Series when
you need:
• Superior application availability at the WAN edge:
guarantee high-priority applications by creating a
virtual "glass ceiling" for lower-priority applications .
• Multiservice, scalable, and secure headend:
The Cisco ASR 1000 Series offers full-service
IP Security (IPsec) VPN aggregation that scales
to meet the new bandwidth demands of service
provider IP VPNs .
• Embedded high-speed firewall: With the Zone-
Policy Firewall, the Cisco ASR 1000 Series acts as
an implicit complete barrier between any interfaces
not members of the same zone .
• Managed CPE: This implementation of branch
architecture offers powerful investment protection
with services and scale .
• Broadband L2TP access concentrator (LAC) or
L2TP Network Server (LNS): Layer 2 Tunneling
Protocol (L2TP) endpoint to tunnel Point-to-Point
Protocol (PPPoX) or IP sessions with bandwidth
demands in the STM-1 ATM, Fast Ethernet, Gigabit
Ethernet, and 20 Gigabit Ethernet range

Branch
Cisco ASR 1000 Series
• Service provider edge: Layer 3 VPN (L3VPN)
provider edge: Example: Distributed provider
edge, or provider edge in global VPN networks
for bandwidth demands such as asymmetric DSL
(ADSL), T1/E1, STM-1, STM-4, Fast Ethernet, Gigabit
Ethernet, etc .
• Service provider edge: High-end route reflector:
As a route reflector for bandwidth support of
10 Gbps
• Next-generation voice and multimedia example:
Cisco Session Border Controller (SBC): The SBC
implementation performs the voice and video
gateway functions simultaneously with regular IP
data services . No appliance or additional service
blade is required . The control protocols and media
protocols work transparently within a complex voice
architecture .
Solution Objective
• Scalable routing platform for legacy or
traditional WAN aggregation
Solution Benefits
• Scalable WAN aggregation/routing
• Scalable legacy WAN technology such
as cRTP, FRF.12, and MLP
• QFP optimizes QOS and Multicast
• Efficient and on demand Netflow cache
storage up to full sampling for any
chache scheme
• PFR monitored prefix and top talkers
