The goal of the article is to install Cisco Cloud Services Router (CSR) 1000v on VMware Virtual Machine and connect CSR 1000v router to the Cisco 3725 router running inside GNS3. Testing transfer of multicast and 802.1Q tagged traffic between the routers is explained in the upcoming tutorial.
The LAB Software Requirements
- Linux Fedora 17 x86_64
- Cisco CSR 1000v - IOS XE Release 3.9.1S
- VMware player 5.0.2 x86
- Graphical Network Simulator GNS3 0.8.4
- Dynamips 0.2.8-RC7-x86_64
- Cisco IOS c3725-adventerprisek9-mz.124-15.T14.bin
The introduction part defines Cisco CSR 1000v and its use. It quotes passages presented in Cisco CSR 1000v - Series Cloud Services Router Software Configuration Guide. The guide is available here:
Introduction
The Cisco Cloud Services Router (CSR) 1000v is a cloud-based router that is deployed on a virtual machine (VM) instance running on x86 server hardware. It contains selected features of the Cisco IOS-XE Operating System and it is intended for deployment in cloud data centers.
One of the main benefits of Cisco CSR 1000v is hardware independence. Once it is installed into virtual machine, it can use any x86 hardware supported by virtualization platform.
The Cisco CSR 1000v running Cisco IOS XE Release 3.9S Hardware Requirements
1. Cisco CSR 1000v Requirements
- Server running the VMware ESXi 5.0
- PC running the VMware vSphere Client 5.0 application for creating, configuring and managing VMs on the VMware vCenter Server
- Installation Tool - VMware vCenter
2. Server Requirements
The Cisco CSR 1000v only operates only with Intel Nehalem and later generation processors.
- AMD processor based servers are not supported.
- The Cisco CSR 1000v uses instructions not supported on Intel pre-Nehalem generation processors. The existence of the required Nahalem or later processor instruction set is determined at boot time. If the required instructions are not present, the following message will displayed:
%IOSXEBOOT-4-BOOT_HALT: (rp/0): Halted boot due to missing CPU feature requirement(s)
3. Virtual Machine Requirements
- 8 GB virtual disk
- 4 vCPUs
- 4 GB of RAM
- 3 or more virtual network interface cards
Cisco CSR 1000v Installation
According to Cisco CSR 1000v Software Configuration Guide, VMware ESXi 5.0 virtualization platform must be used in order to deploy the CSR 1000v router. However I was able to install and run the router using VMware player. Although the player is feature limited it is free for non-commercial use and can be used to run Cisco CSR 1000v router in lab environment.
1. Download and Install VMware-Player-5.0.2
The VMware Player for Linux 64-bit can be downloaded here. Once a file is downloaded assign run privileges to the file.
$ chmod +x ./VMware-Player-5.0.2-1031769.x86_64.bundle
Run the VMware installer launcher as root and graphical installer installs VMware player.
$ sudo ./VMware-Player-5.0.2-1031769.x86_64.bundle
Picture 1 - Install Menu
Once VMware player is installed three interfaces - vmnet0, vmnet1 and vmnet8 are created. They are mapped to the CSR 1000v interfaces as following:
vmnet 0 - GigabiEthernet 0
vmnet 1 - GigabitEthernet 1
vmnet 8 - GigabitEthernet 2
The interface vmnet0 is reserved for connecting Virtual Machine to the host system. This interface is not presented in the output of ifconfig command. It cannot be used to connect CSR 1000v to routers running inside GNS3. As it will be shown later in the tutorial we will use the interface for connecting Cisco CSR 1000v to the Internet.
Other two interfaces created during VMware player installation - interfaces vmnet1 and vmnet8 are presented in the host system. They can be used to connect CSR 1000v to devices running inside GNS3.
Picture 2 - Interfaces vmnet1 and vmnet2 presented in Fedora Linux
Note: If you want to have more than 3 vmnet network interfaces, read this article.
Navigate to File-> Player Preferences and Check Return to the VM Library after closing a virtual machine. It will prevents to close VMware Player once the Virtual machine is powered off.
2. Download and Install Cisco CSR 1000v
Cisco CSR 1000v router can be downloaded here. Select the option Cisco CSR 1000v Series Advanced Enterprise Services - ISO and hit the Download button. The CSR 1000v ISO file can be downloaded for free but you must log in with your free cisco.com account.
Picture 3 - Cisco CSR 1000v Release 3.9.1S ED Download Page
Start VMware player with the command.
$ /usr/bin/vmplayer
Navigate to File -> Create New virtual machine. Select the path to Cisco CSR 1000v ISO image and continue pressing the Next button.

Picture 4 - Guest Operating System Configuration
Assign 8 GB HDD space for the VMware Virtual machine.
Picture 5 - Virtual Disk Size Configuration
Click on the Customize Hardware button.
Picture 6 - Customize Hardware Window
Assign 4096 MB RAM for the Virtual machine.
Picture 7 - RAM Configuration
Select Processors option from the left panel. Increase the number of processor cores to 4.
Picture 8 - Processor Configuration
Navigate to the Network Adapter configuration. The network adapter represents the interface vmnet0. Change the default NAT mode to bridged mode under Network Connection option. Once you do it, interface vmnet0 is automatically bridged to the host Ethernet interface. In my case, the Ethernet interface presented in the host network configuration is named p3p1.
Picture 9 - Network Adapter Configuration
Click on the Add button to add another two network adapters. Change the default NAT mode to host-only mode for the both interfaces. Always use the host-only type of a network connection for Virtual machine interfaces that connect Cisco CSR 1000v Gig Ethernet interfaces to devices running inside GNS3.
Picture 10 - Adding Network Adapter to Virtual Machine
Once you finished the following hardware should presented in your virtual machine inventory. The network adapter 2 represents the interface vmnet1 and network adapter 3 represents the interface vmnet8.
Picture 11 - Virtual Machine Inventory
Left click on VM you have just created and select Play Virtual machine. The installation process begins.

Do not interrupt installation process, Cisco CSR 1000v router will be installed without user intervention. Once the router is installed it will reboot and start up.

Connecting Cisco CSR 1000v to the Cisco 3725 router
A Cisco 3725 multiservice access router is the router that is emulated by Dynamips and running inside GNS3. Connection between the Cisco 3725 and the Cisco CSR 1000v routers is shown on the picture below.
Picture 14 - Network Topology
The Cisco 3725 router is occupied with NM-16SW network module that offers 16 FastEthernet switchports. The module is added to the slot 1 of the router. Left click on the router and select Configure. Under Slot tab select NM-16SW from the list.
Picture 15 - Cisco 3725 router occupied with NM-16SW
As VMware is not integrated in to GNS3, the cloud device must be used to connect both routers. Left click on the cloud and choose Configure. Navigate to NIO Ethernet tab and select the interface vmnet1 from the list. Once you press Add and Apply buttons, the cloud device connects interface vmnet1 and NIO Ethernet.
Picture 16 - Cloud configuration
Now you can connect the Cisco 3725 router interface FastEthernet 1/0 to the cloud interface NIO Ethernet. The cloud device creates a connection between NIO Ethernet and the interface vmnet1. The VMware player itself connects the interface vmnet1 to Cisco CSR 1000v interface GigabitEthernet 1. The connection is established between the routers.

Nice lab Brezular.
Hi,
I folow all the steps, seems perfect, but regarding csr1000v into the interfaces dosn't appear the same as you....appears GigabiEthernet 1 GigabitEthernet 2 GigabitEthernet 3, why dosn't me appear the "GigabiEthernet 0" and after even if "GigabiEthernet 1" it's the same than "GigabiEthernet 0" when I made show run dons't appear "vrf forwarding Mgmt-intf" and I think that will appear. Could u help me please :s?
thanks
