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.

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.

The Cisco IOS XRv 9000 Router offers a flexible licensing scheme, with multiple tiers to choose from, such as Scale, and Throughput. This table lists details of Cisco IOS XRv 9000 Router's pool of software licenses or entitlements, arranged according to licensing PIDs.

Note	The XRv9000 router only consumes and reports VPE licenses. VRR licenses are not consumed or reported.

Cisco IOS XRv 9000 supports these features in release 6.0.0

• Internet Protocol Service Level Agreement (IPSLA)—IPSLA permanent port configuration is supported on a global VRF only. Support for ICMP and MPLS LSP is not available in this release.

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

  Traditional CLI-based configurations, are proprietary, cumbersome, and highly text-based. Managing automated 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 Network Configuration Protocol (Netconf) or with gRPC (google-defined Remote Procedure Calls) to automate programmable network operations. Data models allow administrators to customize settings easily and automatically, without wasting time on manual configuration.

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

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

  Tuning a network based on real-time data is crucial for seamless operation of the network. Instead of a pull model, using a push model to continuously stream data out of the network in the order of few seconds enhances the operational performance and reduces the troubleshooting time. Data can be pushed out at intervals determined by the administrator, at a cadence as low as 30 seconds. Using sophisticated algorithms, 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). This analysis enables back-end management systems to measure and even predict control-plane and data-plane trends.

  A telemetry policy file is used to define the data to be generated and the cadence at which the data is to be streamed. To create a policy file and get started with streaming telemetry data, see the Create Policy File 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 scale limitation.

• 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 over GRE 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, is not supported. At the tunnel destination router, forwarding of the GRE payload packet to another router is 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 destined for tunnel end-point)

  • IPv4 GRE encapsulation including IPv4 payload

  • IPv4 GRE encapsulation including IPv6 payload

  • OSPF over GRE

  • OSPFv3 over GRE

  • ISISv4 over GRE

  • ISISv6 over GRE

  • BGP over GRE

  • L3 load balancing of GRE traffic over multiple egress paths (for tunnel destination)

  • L3 load balancing of non-GRE traffic over multiple egress GRE tunnels

  • GRE interface statistics

  • GRE keepalive

  • Jumbo frame (1500-9000 bytes) with DPDK version 2.0

  • Configuring tunnel MTU

  • Maximum 512 GRE tunnel interface

  • IP precedence preservation

  • Fragmentation (before GRE encapsulation)
