Cisco IOS-XE® Software Release 3.10

The Cisco Cloud Services Router (CSR) 1000V is a single-tenant router in virtual form-factor that delivers comprehensive WAN gateway functionality to multi-tenant provider-hosted clouds. Using familiar, industry-leading Cisco IOS® Software networking capabilities, the CSR 1000V enables enterprises to transparently extend their Wide Area Networks into external provider-hosted clouds and cloud providers to offer enterprise-class networking services to their tenants.

Businesses, small and large, are increasingly virtualizing their data center infrastructures and applications, to save costs and become more agile. 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.

However, the shared-infrastructure shared-resource cloud environment poses networking and security problems to enterprises. First, an enterprise does not have ownership of its cloud connectivity, so cannot extend its network configuration into the cloud. Next, it does not enjoy the same levels of privacy and security for its cloud deployment as it does in its premises. Third, it cannot directly connect its distributed sites to its cloud applications - having to instead backhaul all network traffic through its data center - because it lacks a network-aware endpoint in the cloud. The cloud also presents networking challenges to cloud providers. The primary concern is the scale limitations of the current network switching architecture. The cloud provider also lacks all the components of an end-to-end managed connectivity service offering to its customers, including Quality of Service (QoS), application visibility and Service Level Agreements (SLA).

The Cisco CSR 1000V addresses these cloud-based networking and security constraints. Built on the same proven Cisco IOS® Software platform that is inside the Cisco Integrated Services Router (ISR) and Aggregation Services Router (ASR) product families, it offers a rich set of features, including routing, VPN, firewall, NAT, QoS, application visibility, failover and WAN optimization. These functions empower enterprises and cloud providers to build highly secure, optimized, scalable and consistent hybrid networks.

Product Overview and Benefits

The Cisco CSR 1000V is a software router that an enterprise or a cloud provider can deploy as a virtual machine (VM) in a provider-hosted cloud. It can run on Cisco UCS® servers or servers from leading vendors that support VMware ESXi, Citrix XenServer or Red Hat KVM virtualization. It contains Cisco IOS® Software networking and security features.

A typical cloud provides IT infrastructure and resources to multiple customers or tenants. The Cisco CSR 1000V serves primarily as a router per tenant (Figure 1). That is, each tenant gets its own routing instance, hence its own VPN connections, firewall policies, QoS rules, access control, and so on.

Following is how you could use the Cisco CSR 1000V in a cloud:

Secure VPN Gateway: The CSR 1000V offers route-based IPSec VPNs (DMVPN, EasyVPN, FlexVPN), and in the future, SSL VPN, along with the Cisco IOS® Zone-based Firewall and access control, enabling an enterprise to connect distributed sites directly to its cloud deployment (Table 1).

Benefits of CSR1000v

An enterprise needs to securely connect its premises with its off-premises cloud: A typical large enterprise has a central headquarters, a few regional hubs, two or more data centers, and hundreds to thousands of branch office sites. The network is either hub-and-spoke or fully meshed. By extending the data center to the cloud, the enterprise wants the cloud to act as another node in its network.

DM VPN
Easy VPN
Flex VPN
BGP
OSPF
EIGRP
Zone-based Firewall
ACL
AAA
NAT
DHCP
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 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 WAN Endpoint: The CSR 1000V can serve as an MPLS router that will enable a service provider to offer end-to-end managed connectivity (customer site to customer cloud deployment) with performance guarantees. Also, by extending the MPLS WAN deeper into the cloud network, the service provider can increase network scale - more tenants and more networks per tenant (Table 2).

Features

Benefits of CSR 1000V

A service provider needs to extend MPLS connectivity to its customers’ cloud segments: Service providers who offer managed connectivity service to businesses want to help their customers connect with off-premises clouds. In order to provide end-to-end connectivity, the service providers want to extend their private MPLS WANs into the clouds right up to the edge of the customers’ segments within the clouds.

VRF
BGP
GRE
QoS
IP SLA
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 (CE) 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 CE or as a Provider Edge (PE) extension, can help overcome these scale limitations by creating routing overlays within the cloud, minimizing the providers’ dependence on VLANs.

Layer 2 (VM Migration) or Layer 3 Extension (IP Mobility) from Premise to Cloud: The CSR 1000V offers features such as NAT and LISP that will enable an enterprise to maintain addressing consistency across premise and cloud as it moves applications back and forth or bursts compute capacity into the cloud. The CSR 1000V’s OTV and VPLS features enable an enterprise to extend VLAN segments from its data center into the cloud for server backup, disaster recovery and compute scale (Table 3).

Features

Benefits of CSR 1000V

An enterprise needs to maintain IP addressing consistency when moving an application from its data center into an off-premises cloud: An enterprise does not want to re-configure its application when it moves the application back and forth between its data center and external cloud. Change in the address of the application affects connectivity with the user accesing the application.
NAT
LISP
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 that enables an application to be transported across the tunnel with a fixed identifier.
An enterprise needs to replicate its VMs (for e.g. application servers, web servers, etc.) in an off-premises cloud: An enterprise wants to extend VLAN segments from its data center into an external cloud in order to migrate or back up VMs.
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 that enables a VLAN to be extended to the cloud.

Control Point for Networking Services: The CSR 1000V can redirect traffic to Cisco vWAAS appliances deployed in the cloud. The Application Visibility & Control (AVC) feature of the CSR 1000V offers end-to-end application visibility, performance monitoring and control, allowing service providers to pinpoint application performance problems and offer performance SLAs that can be easily tracked (Table 4).
