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.

New Features Supported in Release 6.0.1

  • The Two-Way Active Measurement Protocol (TWAMP)—TWAMP defines a flexible method for measuring round-trip IP performance between any two devices.

    Advantage of TWAMP:

    • TWAMP enables complete IP performance measurement.

    • TWAMP provides a flexible choice of solutions as it supports all devices deployed in the network.

  • Hierarchical QoS—Hierarchical QoS allows you to specify QoS behavior at multiple policy levels (upto 3 levels), which provides a high degree of granularity in traffic management. Support for 3L hierarchical queueing QoS policies includes queue collapse, skewed queueing and port shaper policies.

  • BGP Optimal Route Reflector (ORR)—BGP ORR feature enables vRR to calculate the bestpath from the point of view of a RR client.

    Advantages of BGP ORR:

    • calculates the bestpath from the point of view of a RR client.

    • enables vRR to be placed anywhere in the topology or in a SP data center.

    • allows SPs to scale memory and CPU usage of RR deployments.

  • Multi Socket Scale Out—The Cisco XRv 9000 router installed using vRR image variant is supported across one or two sockets.

  • In this release minimum 2 virtual CPUs, 8GB memory, and 45G disk is supported for vPE and vRR image variants.

System Requirements

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.

Table 2. Support Matrix for Hypervisor Versions

Virtual Machines

Cisco IOS XRv 9000 Router virtual machines must meet the following requirements:

Table 3. VM Requirement for VMware Environment

Parameters

Supported

VMware ESXi

Version 6.5, 6.7, 7.0 and later

Virtual CPU cores

1 socket with a minimum of 2 cores

Note

 

For production environment minimum of 4 cores is recommended.

Virtual Machine memory size

Virtual Machine hard disk size

Virtual Interfaces

VMXNET3 for traffic interfaces only

Physical NICs

For pass-through:

  • Intel i350 Quad Port 1Gb Adapter

  • Intel Dual Port 10 GbE Ethernet X520 Server Adapter

  • Intel 4 port 10GE Fortville

    Note

     

    PCI passthrough only. SRIOV is not supported.

Note

 

  • Intel Forville has a lower forwarding capability (for high throughput applications in vPE profiles) when compared with Intel 82599 10GE Controller.

Cisco UCS Virtual Interface Card (VIC) 1225

Note

 

If you are configuring LLDP on Cisco IOS XRv 9000, then you must first disable LLDP in the Cisco UCS VIC 1225 via Cisco Integrated Management Controller (CIMC).

Number of interfaces

Minimum of 4 NICs where:

  • 1 for management

  • 2 are reserved

  • 1 for traffic

Maximum of 11 NICs where:

  • 1 for management

  • 2 are reserved

  • 8 for traffic

Default video, SCSI controller set

Required

SCSI controller not required for IDE disk.

IDE hard disk

Single IDE hard disk

Note

 

Multiple hard disk drives on a VM are not supported.


Note

The maximum traffic performance with pass-through NIC interfaces in ESXi is lower than the performance that can be achieved in KVM environments. This is because it is not possible to configure 1G huge-pages in the ESXi hypervisor (as of VMware ESXi 6.0).

Table 4. VM Requirement for KVM Environment

Virtual CD/DVD drive installed

Virtual CD/DVD drive is required for ISO installation


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.
