Cisco IOS XRv 9000 Router is a cloud-based router that is deployed on a virtual machine (VM) instance onx86 server hardware running 64-bit IOS XR software. Cisco IOS XRv 9000 Router provides traditionalProvider Edge (PE) services in a virtualized form factor, as well as virtual Route Reflector (vRR) capabilities.

Cisco IOS XRv 9000 Router OverviewCisco IOS XRv 9000 Router provides traditional Provider Edge services in a virtualized form factor, as wellas virtual Route Reflector capabilities. 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. TheIOS XR features available on the Cisco IOS XRv 9000 Router are discussed in Supported Cisco IOS XRTechnologies , on page 11 section.

When the Cisco IOS XRv 9000 Router virtual IOS XR software is deployed on a VM, the Cisco IOS XRsoftware functions just as if it were deployed on a traditional Cisco IOS XR hardware platform. The CiscoIOS XRv 9000 Router combines Route Processor, Line Card, and virtualized forwarding capabilities into asingle, centralized forwarding instance. The Cisco IOS XRv 9000 Router has a fully featured, high speedvirtual x86 data plane.

Cisco IOS XRv 9000 Router supports the same control plane and data plane features and configurations thatare supported on the Cisco ASR 9000 Series Aggregation Services Routers. Cisco IOS XRv 9000 Router doesnot support hardware specific configurations. The configuration commands for control plane and data planefeatures follow the same syntax as the Cisco ASR 9000 Series Aggregation Services Routers. See Cisco ASR9000 Series Aggregation Services Routers command references for more information on configurationcommands.

Cisco IOS XRv 9000 Router Licensing ModelBeginning with Cisco IOS XR Release 5.4, the Cisco IOS XRv 9000 router supports activation using CiscoSmart Licensing. The Cisco IOS XRv 9000 router licensing includes demo and production modes.

• Data Models—Data models are a programmatic and standards-based way of configuring and collectingoperational data of a network device, replacing the process of manual configuration. Using Data models,Cisco IOSXR operating system supports the automating of configurations that belong to multiple routersacross the network. Data models are written in a standard, industry-defined language, which can definea new configuration and state an existing configuration on a network.

Traditional CLI-based configurations, are proprietary, cumbersome, and highly text-based. Managingautomated operations on a large network using CLIs is a challenge.

Cisco IOS XR supports the YANG data modeling language. YANG can be used with the NetworkConfiguration Protocol (Netconf) or with gRPC (google-defined Remote Procedure Calls) to automateprogrammable network operations. Data models allow administrators to customize settings easily andautomatically, without wasting time on manual configuration.

• Telemetry—Streaming telemetry lets users direct data to a configured receiver for analysis andtroubleshooting purposes in order to maintain the health of the network. This is achieved by leveragingthe capabilities of machine-to-machine communication.

Traditionally, organizations used the pull model to collect data, where a client pulls data from networkelements. This pull model, however, does not scale when there is more than one network managementstation in the network. These traditional techniques do not cater to all the underlying information of therouter, and they require manual intervention.

Tuning a network based on real-time data is crucial for seamless operation of the network. Instead of apull model, using a push model to continuously stream data out of the network in the order of few secondsenhances the operational performance and reduces the troubleshooting time. Data can be pushed out atintervals determined by the administrator, at a cadence as low as 30 seconds. Using sophisticatedalgorithms, a back-end server can then analyze data received from the Cisco IOS XR operating system.The data can be encoded in JavaScript Object Notation (JSON) or Google Protocol Buffers (GPB). Thisanalysis enables back-endmanagement systems to measure and even predict control-plane and data-planetrends.

A telemetry policy file is used to define the data to be generated and the cadence at which the data is tobe streamed. To create a policy file and get started with streaming telemetry data, see the Create PolicyFile section in Cisco IOS XR Telemetry Configuration Guide.

• The minimum virtual machine memory size supported in release 6.0.0 is 8GB with lower route scalelimitation.

• Generic routing encapsulation (GRE)—Cisco IOS XRv 9000 supports GRE slowpath in this release.GRE slowpath supports transport of tunnel source router generated IPv4 or IPv6 unicast packets overGRE tunnel to the tunnel destination router using IPv4 GRE encapsulation. At the tunnel source router,only locally generated or injected IPv4 or IPv6 packets (like ping packets or routing protocol packets),over GRE is supported. Forwarding of packets received from another router, over the GRE tunnel, isnot supported. At the tunnel destination router, forwarding of the GRE payload packet to another routeris not supported.

Supported GRE features include:

• Point-to-point GRE tunnel

• Unicast traffic over GRE

• Slow-path GRE (Carrying packets generated at tunnel source; terminating payload packets destinedfor tunnel end-point)

• IPv4 GRE encapsulation including IPv4 payload

System Requirements

Hypervisors

A hypervisor enables multiple operating systems to share a single hardware host machine.While each operatingsystem appears to have the dedicated use of the host's processor, memory, and other resources; the hypervisorcontrols 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 IOSXRv 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, orVirtual Box. The following table lists release specific supported hypervisor versions.

The tool has provision to filter bugs based on credentials to provide external and internal bugviews for the search input.

Use the BST to view the list of outstanding and resolved bugs in a release.

The BST is available at Bug Search. To search for a specific bug, go to https://tools.cisco.com/bugsearch/bug/bugid. For more information on BST, see Bug Search Help.

Search Bugs in BST

Follow these instructions to search for bugs that are specific to software release in BST.

Step 1 Go to https://tools.cisco.com/bugsearch/.Log in to the tool using your Cisco.com user name and password. After successful login, the Bug Search Tool pageopens.

Step 2 To search for release bugs, enter the following parameters in the page:

• Product―Select Series, enter in the text box. You can alternately navigate to the product name from the Select fromlist link.

• Releases―Enter .

• Show Bugs―Select Affecting or Fixed in these Releases.

Step 3 Press Enter.Note • By default, the search results include bugs with all severity levels and statuses, and bugs that were modified

during the life cycle of the bug. After you perform a search, you can filter your search results to meet yoursearch requirements.

• An initial set of 25 search results is shown in the bottom pane. Drag the scroll bar to display the next setof 25 results. Pagination of search results is not supported.
