Delivering enterprise-class networking to the cloud with rapid deployment and flexibility

The Cisco® Cloud Services Router 1000V (CSR 1000V) is a router and network services platform in virtual form factor that is intended for deployment in cloud and virtual data centers.

It is optimized to serve as a single-tenant or multitenant WAN gateway. Using proven, industry-leading Cisco IOS® XE Software and Cisco SD-WAN networking and security features, the CSR 1000V enables enterprises to transparently extend their WANs into external provider-hosted clouds and cloud providers to offer their tenants enterprise-class networking services.

Benefits

      Rapid deployment and service automation: Virtual form factor accelerates deployment and eliminates hardware costs such as complete equipment upgrades and Return Material Authorizations (RMAs).

      Single-tenant use: This feature allows a cloud service provider to provision a routing instance per tenant, simplifying service delivery and tenant management. It also helps the provider overcome VLAN scale limits, increasing tenant scale.

      Enterprise network extension to the cloud: This feature provides enterprises highly secure direct connections from their distributed sites to their cloud-hosted applications, improving application response time and user experience.

      Network consistency: This feature uses familiar enterprise-class Cisco IOS Software features for consistent network operation across premises and cloud, allowing the enterprise to view the cloud as just another node in its network.

      Network scalability: Scale beyond the limitations of 802.1q VLAN tagging by building a VXLAN network, or extending Layer-3 routing deeper into the cloud environment.

      Consolidation of network functions: Eliminate the facility requirements and complexity of physical network devices by consolidating multiple network functions onto a single piece of server hardware.

Use cases

The Cisco CSR 1000V is a software router that an enterprise or cloud provider can deploy as a virtual machine in a provider-hosted cloud (Figure 1 and 2) for the following uses:

      Highly secure VPN gateway: Route-based IP Security (IPsec) VPNs, Dynamic Multipoint VPN (DMVPN), Easy VPN, Secure Sockets Layer (SSL) VPN, and FlexVPN, along with the Cisco IOS Zone- Based Firewall and access control, enable an enterprise to connect distributed sites directly to its cloud deployment.

      Multiprotocol Label Switching (MPLS) extension: This MPLS customer-edge or provider-edge router enables a service provider to offer a customer end-to-end managed connectivity. Also, by extending the MPLS WAN deeper into the cloud, the provider can increase tenant scale.

      IP mobility and virtual-machine migration: Locator/ID Separation Protocol (LISP) enables an enterprise to maintain addressing consistency when moving applications into the cloud. Overlay Transport Virtualization (OTV) enables an enterprise to extend Layer-2 VLANs from data center to cloud.

      Traffic control and redirection: The Cisco CSR 1000V includes networking services such as Hot Standby Router Protocol (HSRP) and Cisco Application Visibility and Control (AVC), enabling a cloud tenant to receive a comprehensive networking experience. IT can also redirect traffic to Cisco Virtual Wide Area Application Services (vWAAS) or Cisco WAAS appliances.

      Virtual Extensible LAN (VXLAN) gateway: You can expand network scalability by using VXLAN isolation instead of 802.1q VLANS.
