Because of the advanced capabilities in the Cisco ASR 1000 Series Route Processors, many additional features
are performed in line with routing, including:
●
Building and distributing forwarding information to the Cisco ASR 1000 Series Embedded Services
Processor (ESP)
●
Implementing session border controller (SBC) setup and teardown and applying per-session policies for
voice and video streams
●
Offering a portal for stateful firewall policy configuration and distribution to the ESP forwarding engine
●
Negotiating and maintaining IP Security (IPsec
) authentication, encryption methods, and encryption keys
(Internet Key Exchange [IKE])
As the management processor for the Cisco ASR 1000 Series Router, the Cisco ASR 1000 Series Route
Processors automatically perform the following system management functions:
●
Load the operating system software system images to all installed line cards upon powering up or through
operator commands
●
Synchronize the dynamic state conditions for the redundant Cisco IOS XE Software, the route processor,
and embedded services processor components
●
Perform high-availability failover for redundant solutions
●
Provide out-of-band system console and auxiliary ports, USB, and Ethernet ports for router configuration
and maintenance
●
Allow direct system access through the operating-system kernel if catastrophic Cisco IOS Software failure
occurs
●
Monitor and manage the power and temperature of system components such as line cards, power supplies,
and fans
Table 1 gives features and benefits of the Cisco ASR 1000 Series RP1.
Table 1. Features and Benefits of Cisco ASR 1000 Series RP1
Support for Cisco IOS XE
Software
●
Supports a breadth of IP network services, including quality of service (QoS), MPLS, Layer 2 virtual private
network (L2VPN), Layer 3 virtual private network (L3VPN), and IPv6
●
Uses the field-proven Cisco IOS Software for all IP network services
●
Provides optional redundant-processor support and dual Cisco IOS Software support for single-route-processor
solutions for a highly compact, fully redundant, high-availability solution, improving network resiliency,
management, and costs
Stratum-3 clock circuitry
and BITS input ports
●
Facilitates support of clocking for synchronous services such as SONET and SDH
Memory scalability of up
to 16 GB
●
Allows pay-as-you-grow scalability so memory can increase as more users or features are added; the scalability
offered through memory upgrades includes:
◦ Routing-table growth
◦ Additional MPLS VPN routing and forwarding instances
◦ Feature additions such as SBC and broadband aggregation (BBA)
This product includes software developed by Cavium Networks.
