The Cisco IOS XRv router is a Virtual Machine (VM) based platform running 32-bit Cisco IOS XR software with the QNX microkernel. This VM contains a single Route Processor (RP) with control plane functionality and Line Card (LC) network interfaces with their associated functionality.
Cisco IOS XRv Overview
Cisco IOS XRv router runs the Cisco IOS XR software and operating system on generic virtualized hardware based on Cisco IOS XR Software. It is provided as a virtual machine (VM) supporting full virtualization, and can be deployed on any x86 hardware (server or laptop) running standard hypervisors. It provides the functionality of a route processor and a line card in a combined route processor line card (RPLC) with both the route processor control plane functionality and the network interfaces and associated LC functionality running on the same virtual card.
Cisco IOS XRv router is a representation of the Cisco IOS XR Software and operating system, and does not provide a virtual representation of any physical router. As a result, some physical system components, such as line cards, fabric cards, and multichassis, that are not appropriate for the VM setup, are not present in the Cisco IOS XRv router system.
Cisco IOS XRv supports the same control plane features and configurations that are supported on the Cisco ASR 9000 Series Aggregation Services Routers and Cisco CRS Routers. Cisco IOS XRv router does not support data plane and hardware specific configurations. The configuration commands for control plane features follow the same syntax as the Cisco ASR 9000 Series Aggregation Services Routers and Cisco CRS Routers. See Cisco ASR 9000 Series Aggregation Services Routers and Cisco CRS Router command references for more information on configuration commands, at this link: http:/?/?www.cisco.com/?c/?en/?us/?support/?ios-nx-os-software/?ios-xr-software/?products-command-reference-list.html.
Cisco IOS XRv routers do not support Layer 2 features.
The Cisco IOS XRv router provides these benefits of virtualization in the cloud environment.
Hardware independence-The Cisco IOS XRv router runs on a virtual machine, therefore, can be supported on any x86 hardware supported by the virtualization platform.
Sharing of resources-The resources used by the Cisco IOS XRv router are managed by the hypervisor, and can be shared among VMs. The amount of hardware resources that the VM server allocates to a specific VM, can be reallocated to another VM on the server.
Flexibility in deployment-You can easily move a VM from one server to another. Thus, you can move the Cisco IOS XRv Router from a server in one physical location to a server in another physical location without moving any hardware resources.
The Cisco IOS XR Software running on the Cisco IOS XRv router provides the following features:
IP features-Supports a wide range of IPv4 and IPv6 services and routing protocols such as IPv4 unicast services, IPv6 unicast services, IPv4 Multicast services, IPv4 and IPv6 equal-cost multi-path (ECMP), IPv4 and IPv6 load balancing, Cisco Discovery Protocol, IPv4 and IPv6 addressing, and Internet Control Message Protocol (ICMP).
Layer 3 routing protocols-Supports routing protocols such as Border Gateway Protocol Version 4 (BGPv4), Open Shortest Path First Version 2 (OSPFv2) and Version 3 (OSPFv3), and Intermediate System-to-Intermediate System (IS-IS) protocol.
Multiprotocol Label Switching (MPLS) Features-Supports MPLS features such as MPLS Label Distribution Protocol (LDP), Resource Reservation Protocol (RSVP), Diffserv Aware Traffic Engineering (TE), MPLS Traffic Engineering control plane (RFCs 2702 and 2430), MPLS forwarding and MPLS load balancing.
Network Management-This supports features like Enhanced CLI, XML interface and Simple Network Management Protocol (SNMP) support.
Software Maintenance Update (SMU)-Support for applying fixes for software defects between releases.
