Cisco Cloud Services Router 1000V IP Base Package E-PAK - Subscription License (3 Years) - 2.5 Gbps - ESD - L-CSR-2.5G-IPB-3Y=

• Ownership
  An enterprise can deploy a CSR 1000V in the cloud, access its command-line interface (CLI), and manage it using the Cisco Prime Infrastructure.
• Seamless connectivity and enterprise-class scalability
  With its range of VPN and routing features, the CSR 1000V can fit into any enterprise network topology. An enterprise can directly and dynamically connect its distributed sites to its cloud deployment, avoiding the latency caused by the typical backhaul through the data center while overcoming the management complexity of point-to-point IPsec VPNs.
• Consistent WAN architecture
  The Cisco IOS-based CSR 1000V complements the widely deployed Cisco ISRs and ASRs. Enterprises can now deploy a Cisco endpoint at every node in their network, allowing for consistent network configuration and security policies across their distributed hybrid networks.
• MPLS extension within a cloud
  A service provider can manage the cloud connectivity of its customers and offer performance and reliability guarantees with the help of a dedicated CSR 1000V (serving as a customer-edge router) per customer.
• Intra-cloud scale
  A typical cloud network is highly switched. A router hands off incoming traffic to a group of switches, which assign the traffic to customer VLANs. In this network architecture, the cloud provider cannot scale beyond 4.096 VLANs per router, limiting the number of customers it can support. The CSR 1000V, serving as a customer-edge or as a provider-edge extension, can help overcome these scale limitations by creating routing overlays within the cloud, minimizing the providers' dependence on VLANs.
• IP mobility
  The cloud-based CSR 1000V can serve as a LISP router, building a tunnel with a LISP-enabled router in the enterprise's data center so an application can be transported across the tunnel with a fixed identifier.
• VM migration
  The cloud-based CSR 1000V can serve as an OTV router, building a bridge with an OTV-enabled router in the enterprise's data center so that a VLAN can be extended to the cloud.

The Cisco Cloud Services Router 1000V (CSR 1000V) is a virtual form-factor router that delivers comprehensive WAN gateway and network services functions into virtual and cloud environments. Using familiar, industry-leading Cisco IOS XE Software networking capabilities, the CSR 1000V enables enterprises to transparently extend their WANs into provider-hosted clouds. Similarly, cloud providers themselves can use it to offer enterprise-class networking services to their tenants or customers.
To save costs and become more agile, businesses small and large are increasingly virtualizing their data center infrastructures and applications. Many enterprises have started deploying IT applications in virtualized data centers that are built and managed by third-party service providers. These external data centers, known as provider-hosted clouds, allow enterprises to gain infrastructure and resources on demand and become even more operationally efficient.
