Cisco IOS XRv 9000 Router Overview
The Cisco IOS XRv 9000 Router is based on Cisco IOS XR software, so it inherits and shares the wide breadth of routing functionality available on other IOS XR platforms. The IOS XR features available on the Cisco IOS XRv 9000 Router are discussed in Supported Cisco IOS XR Technologies section.
When the Cisco IOS XRv 9000 Router virtual IOS XR software is deployed as a VM, the Cisco IOS XR software functions just as if it were deployed on a traditional Cisco IOS XR hardware platform. The Cisco IOS XRv 9000 Router combines Route Processor, Line Card, and virtualized forwarding capabilities into a single, centralized forwarding instance. The Cisco IOS XRv 9000 Router has a fully featured, high speed virtual x86 data plane.
Cisco IOS XRv 9000 Router supports the same look and feel as Cisco ASR 9000 Series Aggregation Services Routers and North-bound APIs. Cisco IOS XRv 9000 Router does not support hardware specific configurations. The configuration commands for control plane and data plane features follow the same syntax as the Cisco ASR 9000 Series Aggregation Services Routers. See Cisco ASR 9000 Series Aggregation Services Routers command references for more information on configuration commands.
Cisco IOS XRv 9000 Router Licensing Model
The Cisco IOS XRv 9000 Router supports activation using Cisco Smart Licensing. By default the Cisco IOS XRv 9000 Router (without license) is rate limited to 200 Kbps.
For more information on licensing model supported on Cisco IOS XRv 9000 Router, see the Cisco IOS XRv 9000 Router Smart Licensing chapter in the Cisco IOS XRv 9000 Router Installation and Configuration Guide.
See Cisco Smart Software Licensing Overview for more information on Cisco Smart Licensing.

Software Features Introduced in this Release
Segment Routing Features Support on Cisco IOS XRv 9000
Segment routing is a method of forwarding packets on the network based on the source routing paradigm. The source chooses a path and encodes it in the packet header as an ordered list of segments. Segments are an identifier for any type of instruction. For example, topology segments identify the next hop toward a destination. Each segment is identified by the segment ID (SID) consisting of a flat unsigned 20-bit integer.
For more information on Segment Routing, see Segment Routing Configuration Guide for Cisco ASR 9000 Series Routers.
Carrier Supporting Carrier Support for L3VPN
The MPLS VPN Carrier Supporting Carrier (CSC) functionality provides benefits to the backbone carriers and customer carriers. They are:
Benefits to the Backbone Carrier
-
The backbone carrier can accommodate many customer carriers and give them access to its backbone.
-
The MPLS VPN carrier supporting carrier feature is scalable.
-
The MPLS VPN carrier supporting carrier feature is a flexible solution.
Benefits to the Customer Carriers
-
The MPLS VPN carrier supporting carrier feature removes from the customer carrier the burden of configuring, operating, and maintaining its own backbone.
-
Customer carriers who use the VPN services provided by the backbone carrier receive the same level of security that Frame Relay or ATM-based VPNs provide.
-
Customer carriers can use any link layer technology to connect the CE routers to the PE routers .
-
The customer carrier can use any addressing scheme and still be supported by a backbone carrier.
For information on how to enable the MPLS VPN Carrier Supporting Carrier (CSC) functionality, see the Implementing MPLS Layer 3 VPNs chapter in the MPLS Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 7.0.1.
Inter-AS Support for L3VPN
An MPLS VPN Inter-AS allows a VPN to exist in different areas, to cross more than one service provider backbone, and allows confederations to optimize iBGP meshing.
For information on how to enable the Inter-AS Support for L3VPN feature, see the Implementing MPLS Layer 3 VPNs chapter in the MPLS Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 7.0.1.
MPLS Traffic Engineering
MPLS traffic engineering (MPLS-TE) software enables an MPLS backbone to replicate and expand upon the TE capabilities of Layer 2 ATM and Frame Relay networks. MPLS is an integration of Layer 2 and Layer 3 technologies. By making traditional Layer 2 features available to Layer 3, MPLS enables traffic engineering. Thus, you can offer in a one-tier network what now can be achieved only by overlaying a Layer 3 network on a Layer 2 network.
For information on how to enable MPLS TE, see the Implementing MPLS Traffic Engineering chapter in the MPLS Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 7.0.1.
System Requirements
Appliance Model
Cisco IOS XRv 9000 Appliance is the pre-installed Cisco IOS XRv 9000 Router software that is sent from the factory on a bare metal UCS server hardware. It supports hyper scalability as it can scale to 70 Million route prefixes when run as a Virtual Route Reflector. Therefore, the extra layer of software (hypervisor) is not required.
The Appliance also supports Zero Touch Provisioning (ZTP) which allows easier insertion into existing networks. Current offering is based on UCS M5 Servers, comes with 2 Intel X710 quad-port 10G SFP+ NICs.
Hypervisors
A hypervisor enables multiple operating systems to share a single hardware host machine. While each operating system appears to have the dedicated use of the host's processor, memory, and other resources; the hypervisor controls and allocates only needed resources to each operating system and ensures that the operating systems (VMs) do not disrupt each other.
Installation of the Cisco IOS XRv 9000 Router is supported on selected Type 1 (native, bare metal) hypervisors. Installation is not supported on Type 2 (hosted) hypervisors, such as VMware Fusion, VMware Player, or Virtual Box. The following table lists release specific supported hypervisor versions.

Note |
In the Cisco IOS XRv 9000 Router, some CPU cores are dedicated to the control plane while others are dedicated to the data plane. Each data plane's core runs a single thread that performs packet forwarding. To achieve maximum performance, these threads constantly look for data packets to process. As a result, the OS records that these cores run at 100% utilization. This is expected behavior and not an indication that packet forwarding has reached its threshold limit. |
Server
The server must support:
-
Intel Westmere or later CPU versions with clock frequency of 2.0GHz for instances with Gigabit or paravirtualized interfaces
-
Intel Ivy Bridge or later CPU versions for instances with 10Gb or higher interfaces
-
Intel CPU must support the sse4_2 capability flag. This can be checked in KVM by looking for the sse4_2 flag in the flags section of /proc/cpuinfo. For example:
cat /proc/cpuinfo | grep sse4_2 flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon nopl xtopology tsc_reliable nonstop_tsc aperfmperf pni pclmulqdq vmx ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx f16c rdrand hypervisor lahf_lm ida arat epb pln pts dtherm tpr_shadow vnmi ept vpid fsgsbase smep
Note |
To use passthrough interfaces in KVM, you must set the option intel_iommu=on command in the grub configuration. |

Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).
Note |
The FPD related commands are not supported on IOS XRv 9000 Appliance. That includes fpd auto-upgrade command. |
