●   Modular Cisco ASR 1000 Series Route Processors for modular chassis, including the ASR 1004, ASR 1006, ASR 1006-X, ASR 1009-X and ASR 1013 models. These are the Cisco ASR 1000 Series Route Processor 1 (RP1; part number ASR1000-RP1), Cisco ASR 1000 Series Route Processor 2 (RP2; part number ASR1000-RP2), and Cisco ASR 1000 Series Route Processor 3 (RP3; part number ASR1000-RP3)

●   Fixed or built-in Cisco ASR 1000 Series Route Processors for fixed chassis, including the ASR 1001, ASR 1001-X, ASR 1002, ASR 1002-F, and ASR 1002-X models. ASR 1002 and ASR 1002-F contain an embedded RP1 (part number ASR1000-RP1).

Table 1 lists the characteristics and chassis support of Cisco ASR 1000 Series RP1, RP2, and RP3.

●   Optional redundant-processor and dual Cisco IOS XE Software support for single-route-processor solutions to improve network resiliency

●   Hard disk drive (HDD) or solid state drive (SSD) for code storage, boot, configuration, logs, and so on (HDD or SSD are optional on Cisco ASR 1001, 1001-X, 1001-HX, 1002-X, and 1002-HX)

●   USB ports for 1-GB compact flash memory support

●   Built-in embedded flash memory (eUSB or eMMC) support:

◦     1 GB on RP1; 8 GB on the built-in RP1 on the ASR 1002 router partitioned: 1 GB for bootflash; 7 GB for mass storage

◦     2 GB on RP2; 8 GB on RP3

◦     8 GB on the built-in route processor on the Cisco ASR 1001, 1001-X and 1002-X, partitioned: 1 GB for bootflash; 7 GB for mass storage

●   Field-replaceable and hot-swappable capabilities with modular route processors for minimal service disruption

●   Stratum-3 clock circuitry, building integrated timing supply (BITS) input and output (BITS output available on ASR1000-RP2 and on the chassis of ASR1002-X that has a built-in RP)

●   Memory scalability up to 4 GB DRAM on the RP1; up to 16 GB DRAM on the RP2, ASR 1001, ASR 1001-X, ASR 1001-HX, ASR 1002-X, and ASR 1002-HX; up to 64 GB DRAM on the RP3

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^[1]) authentication, encryption methods, and encryption keys (Internet Key Exchange [IKE])

As the management processor for the Cisco ASR 1000 Series Router, the RPs automatically perform the following system management functions:

●   Load the operating system software 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 ESP 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
