Virtual Router

The Cisco Cloud Services Router 1000V (CSR 1000V) is a cloud-based virtual router that is intended for deployment in cloud and virtual data centers. This router is optimized to serve as a single-tenant or a multitenant WAN gateway.

When you deploy a CSR 1000V instance on a VM, the Cisco IOS XE software functions as if it were deployed on a traditional Cisco hardware platform. You can configure different features depending on the Cisco IOS XE software image.

Secure Connectivity

CSR 1000V provides secure connectivity from an enterprise network such as a branch office or a data center, to a public or a private cloud.

Technologies Supported by a Platform

A platform’s product landing page lists technology configuration guides for Cisco IOS XE technologies that the platform supports.

In each technology configuration guide, a Feature Information table indicates when a feature was introduced to the technology. For some features, the table also indicates when additional platforms have added support for the feature.

To determine whether a particular platform supports a technology, view the list of technology configuration guides posted on the platform’s product landing page. For example, see Cisco Cloud Services Router 1000v Series.

System Requirements

Software Images and Licenses

The following sections describe the licensing and software images for CSR 1000V.

Cisco CSR 1000v Evaluation Licenses

Evaluation license availability depends on the software version:

The following evaluation licenses are available:

  • IPBASE technology package license with 10 Gbps maximum throughput

  • SEC technology package license with 5 Gbps maximum throughput

  • APPX technology package license with 5 Gbps maximum throughput

  • AX technology package license with 2.5 Gbps maximum throughput

If you need an evaluation license for the Security technology package, or for an AX technology package with higher throughput, contact your Cisco service representative.

For instructions on obtaining and installing evaluation licenses, see the “Installing CSL Evaluation Licenses for Cisco IOS XE 3.13S and Later” section of the Cisco CSR 1000v Software Configuration Guide .

Cisco CSR 1000v Software Licenses

Cisco CSR 1000v software licenses are divided into feature set licenses. The supported feature licenses depend on the release.

Current License Types

The following are the license types that are supported (Cisco IOS XE Everest 16.4.1 or later):

  • IPBase: Basic Networking Routing (Routing, HSRP, NAT, ACL, VRF, GRE, QoS)

  • Security: IPBase package + Security features (IP Security VPN, Firewall, MPLS, Multicast)

  • AX: IPBase package + Security features + Advanced Networking features (AppNav, AVC, OTV and LISP)

  • APPX Package: IPBase package + Advanced Networking features - Security features (IP security features not supported)

Legacy License Types

The three legacy technology packages - Standard, Advanced, and Premium - were replaced in the Cisco IOS XE Release 3.13 with the IPBase, Security, and AX technology packages.

Features Supported by License Packages

For more information about the Cisco IOS XE technologies supported in the feature set packages, see the overview chapter of the Cisco CSR 1000v Series Cloud Services Router Software Configuration Guide.

Throughput

The Cisco CSR 1000v router provides both perpetual licenses and term subscription licenses that support the feature set packages for the following maximum throughput levels:

  • 10 Mbps

  • 50 Mbps

  • 100 Mbps

  • 250 Mbps

  • 500 Mbps

  • 1 Gbps

  • 2.5 Gbps

  • 5 Gbps

  • 10 Gbps

The throughput levels are supported for different feature set packages in each version. For more information about how the maximum throughput levels are regulated on the router, see the Cisco CSR 1000v Cloud Services Router Software Configuration Guide.

Memory Upgrade

A memory upgrade license is available to add memory to the Cisco CSR 1000v router (Cisco IOS XE 3.11S or later). This license is available only for selected technology packages.

Additional Information about Licenses and Activation

For more information about each software license, including part numbers, see the Cisco CSR 1000v Router Datasheet. For more information about the standard Cisco IOS XE software activation procedure, see the Software Activation Configuration Guide, Cisco IOS XE Release 3S.

Software Image Nomenclature for OVA, ISO, and QCOW2 Installation Files

For detailed information, see the following Cisco document: Transit Virtual Private Cloud Deployment Guide using Cisco CSR 1000v for Amazon Web Services

Notes

The following section includes important notes about Cisco CSR 1000v routers for Cisco IOS XE Everest 16.6.

3DES and AES-CBC Ciphers Disabled

(Cisco IOS XE Everest 16.6.1 or higher) For SSH, the cipher Triple Data Encryption Standard (3DES) and AES Cipher Block Chaining (AES-CBC) ciphers are now disabled by default. We recommend that you use the later Advanced Encryption Standard Counter Mode (AES-CTR) ciphers instead.

If you are using 3DES or AES-CBC ciphers; for example, in SSH client software, the network administrator must change the ciphers to be one of the AES-CTR ciphers used in 16.6.1;that is: aes128-ctr, aes192-ctr, and aes256-ctr.

The following example command defines the ciphers/encryption algorithms to be used by the SSH server and client:

ip ssh client algorithm encryption aes128-ctr aes192-ctr aes256-ctr

For more information on SSH encryption algorithms, see: SSH Algorithms for Common Criteria Certification.
