These single-VM versions of vMX include 14.1R1.10, 14.1R3.5, and 14.1R4.8. By default, these will be called “jinstall-vmx-domesting.img”. When you download the KVM version of vMX, it will come as a roughly 3GB.tgz file. If you have no intention of running vMX on an Ubuntu server, feel free to delete.

GNS3 VMs for both ESX and Workstation along with GNS3 settngs to use. (in preferences, choose import settings. For the remote VM, you will need to replace the Host, look for 1.2.3.4 IP).This is based on 1.4RC2:If you didn’t followed latest GNS News, they now provide a VM that can run QEMU, IOU, and other stuff, while being controlled from GNS3 GUI on your machine.That is either you use a remote server (and put the VM on ESX), or use a local VM with workstation / fusion. The Configuration is still made from your machine, but the virtual appliances runs within the VM.See here for more details:The VM contains tthe following images. The Juniper Firefly Perimeter (vSRX) is available as a virtual router also.

Source: offers its brilliant MX routers for virtual environments – namely. And we cant name ourselves engineers if we wouldn’t try to run one in the. Running vMX in the unetlab is a simple task, yet I see many complaints about vMX not working.

With this being said I invite you to a journey called “running vMX in Unetlab. Painless edition”.

HOW TO GET VMX?Why is this way painless? Mainly because we will run vMX 14.1R1 which has a.vdi image out there in the Internet. I bet you will find your way to this image.If you will go straight to the Junipers product you will be offered 14.1R5 release which comes without single disk image and not so easy to install (see this here to get the details). I wont tell you how to run 14.1R5 in the Unetlab, because (1) I havn’t tried it yet and (2) you cant play with this release without a licence. HOW TO INSTALL VMX IMAGE?Okay, you got vMX.vdi image of Juniper vMX, now it’s time to convert this image to qcow2 file type since this is the preferred image type for qemu hypervisor. Do the following:. convert vdi image to the qcow2.

Root@ubuntu-14:/Juniperimages# qemu-img convert -f vdi -O qcow2 vMX.vdi hda.qcow2You should have hda.qcow2 image now. Use exactly this name – hda.qcow2 – as an output of the convert process, it is a mandatory naming scheme for Unetlab. Create a folder named vmx-14.1.R1 under the /opt/unetlab/addons/qemu/. Mind the folder name, you must keep vmx- at the beginning of the folder name, you can place whatever you want after the hyphen sign. Move hda.qcow2 to the /opt/unetlab/addons/qemu/ and run permission-fixer script. $p‘qemuoptions’ = ‘ -serial mon:stdio -nographic -enable-kvm’;Rumors are that default qemu options are as good as mine, yet I prefer my string with -enable-kvm and without -machine type=pc-1.0,accel=kvm opts.

Testing connectivityTime to add two nodes and test the basic L3 connectivity. As I said, when adding vMX node you can stick to the defaults, or add more CPU if you have them.When you will add bridge network and try to connect vMX interface to it, you will see that first two interfaces are locked down (marked “Do not use”). Do not use them =) I connected thirds interfaces and Unetlab pictured their names as em2/ge-0/0/0. This is because vMX is a running in a linux virtual machine and got its interfaces appropriately named. I configured em# interfaces and not the ge-x/x/x. If you want to configure ge-x/x/x interfaces, you should explicitly configure mac address for every ge interface in use and exclude em interfaces if you configured them earlier.Here is a basic interfaces configuration and test procedure via ping.

Round-trip min/avg/max/stddev = 0.404/0.494/0.691/0.102 msBingo. KNOWN ISSUES & FINAL THOUGHTSI havnt had a lot of time to play with vMX, still I noticed some problems I’d like to share:. When I started nodes simultaneously (by clicking start all nodes) I often ended up with vMX bootlooped. So for a workaround I run the nodes one by one.

If you telnet to a node right after you clicked “Start the node” you could find yourself in a boostrap prompt. So I waited 10 seconds after hit “Run” button till trying to telnet to the device to avoid bootstrap menu. Actually vMX can be equipped with up to 10 GE interfaces. So you can specify 12 interfaces when adding a node and use ifaces from 2 to 12 for interconnection.I don’t know if this release has any limitation regarding some hardcore features like QoS or Multicasts (I heard nothing on that), but routing, MPLS and services work just fine. If you are aware of some limitations, please let us know in the comments.Have fun with Junos, now without the necessity to book JunoSphere. Source: most common for IPv6 (that is: how to enable IPv6 on a network that does not have a native IPv6 connection to the Internet) is a “6in4” tunnel. Even other tunneling methods such as Teredo or are found on different literatures.

However, another method that is not often explained is to tunnel the IPv6 packets through a VPN connection. For example, if the main office has a native IPv6 connection to the Internet, as well as VPN connections to its remote offices, it is easy to bring IPv6 subnets to these stations.Here is how I did it with some Juniper SSG firewalls:I assume that there is already a VPN connection between two Juniper ScreenOS firewalls in place. If so, the steps to tunnel IPv6 through this VPN tunnel are quite easy. (Note that this is NOT a 6in4 tunnel!

It is simply a forwarding of IPv6 packets through a common IPsec site-to-site tunnel.) TunnelingThe following configuration steps are required:. Enable IPv6 in the “host” mode on the tunnel interfaces. Configure static IPv6 routes through these tunnel interfaces. Do regular IPv6 stuff: Enable IPv6 with Router Advertisements at the remote site and configure the appropriate security policiesThis is how my networks look like, followed by the configuration screenshots:(For further information: Read the descriptions under the screenshots.).

And the policy.Done. Latency & Hop CountOne side note about the latency: Yes, since the IPv6 connection must travel through the IPv4 tunnel (with its hops to the main site) as well as through the native IPv6 Internet to the final destination, the total hop count (i.e., latency) is approximately doubled. However, I made an interesting observation: My main site has a quite good ISP connection with almost the same ping times of IPv4 and IPv6 (latency of 3-4 ms). My home site has a normal German DSL connection and I am surfing via WLAN – IPv4 latency of about 23 ms. And now, my new IPv6 connection has an added latency of about 29 ms, which is compared to the native IPv4 connectivity not that bad. Source: to my, I am testing OSPFv3 for IPv6 with the following devices: Cisco ASA, Cisco Router, Fortinet FortiGate, Juniper SSG, Palo Alto, and Quagga Router. I am showing my lab network diagram and the configuration commands/screenshots for all devices.

Furthermore, I am listing some basic troubleshooting commands. In the last section, I provide a Tcpdump/Wireshark capture of an initial OSPFv3 run.I am not going into deep details of OSPFv3 at all. But this lab should give basic hints/examples for configuring OSPFv3 for all of the listed devices. LabThis is my test lab.
