This example configuration shows how to configure ZTP in a typical branch network environment. Network Director is used as the ZTP server. When a switch is connected to the network and powered up with its factory default configuration, the ZTP process on the switch downloads the appropriate software and also the configuration file for the device.

The basic ZTP process provides a standard configuration file based on the type of device. For example, all EX switches must have a specified Junos OS software version and a standardized configuration file intended for EX switches. When bringing up a new device on a network with ZTP, there are two phases. The first phase is the basic ZTP process that includes general provisioning, such as downloading of the proper software and configuration files to the ZTP device.

After the configuration file has been downloaded, the basic ZTP process is completed. The second phase is device-specific, taking advantage of Juniper Networks built-in automation capabilities. During the second phase, the device automatically installs a device-specific configuration based on its location. When the basic ZTP process is complete, the ZTP device has the correct OS for that model and also has a configuration file that is common for that type of platform in a site.

ZTP solutions from most other vendors stop there. However, Juniper Networks devices can go on further. After the device is connected and powered up, there is no need for any additional CLI or GUI intervention to configure the device.

The device has the necessary configuration for the location. The device gets a specific configuration based on where the device is plugged into the network. If this device is removed and another device gets plugged in at this location, that device gets the same specific configuration irrespective of the MAC address or serial number of the device. Configuration The network environment requires some preparation to support the ZTP process.

This section includes procedures that show how to set up the environment to support ZTP, as well as how to actively deploy ZTP in this example. The network administrators can also manually prepare these tasks separately if desired. To configure ZTP involves performing these tasks:.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Network Engineering Stack Exchange is a question and answer site for network engineers. It only takes a minute to sign up. I'm sure there's probably an easy way to do this, but couldn't find it on the Juniper KB or by a minimum amount of Googling. Anyone here know? And then you move that file to the other switch someway, usign ftp, sftp, scp WinSCP, etc.

Worked like a champ! I use the script share-data. This isn't very helpful for the initial config of the switch as you still need to be able to access it and be able to set the apply-group. The previous posters suggestion of scp the config file over would be my suggestion. For four devices applying a default configuration by hand is a good option.

However if you'd like to upgrade or downgrade and apply a default configuration to multiple devices then Zero Touch Provisioning ZTP might be a more convenient solution for Juniper hardware.

KB has some good information regarding the process as well the Configuring Zero Touch Provisioning article. Follow these steps to replicate the configs.

I do not think I saw anyone mention it, another piece of good knowledge to have are the two commands: commit confirm overwrite and commit confirm merge.

These two commands help with similar things the main difference being that the commit confirm merge copies content from another configuration that contains data you want to integrate to your current candidate configuration.

This command does not overwrite any of your current configuration. Commit confirm overwrite does as it sounds and overwrites the current configuration with the new configuration. A rollback would be necessary to revert from this operation. Lastly, when committing any new configuration data, its always good practice to use the commit check command prior to confirming.

That sounds great for config transfers to another switch that's already online, but this case is to configure a new blank switch from another configured switch's setup Good to know tho!Juniper networks have always been a favorite among the service provider crowd. If you take a look at the service provider vertical, it would make sense that automating network equipment is on the top of their list of requirements.

Before the dawn of cloud-scale data centers, service providers were the ones with the most network equipment. A typical enterprise network might have a few redundant internet connections at the corporate headquarter with a few hub-and-spoke remote sites connected back to the HQ using the service provider's private MPLS network. To a service provider, they are the ones who need to build, provision, manage, and troubleshoot the connections and the underlying networks.

They make their money by selling the bandwidth along with value-added managed services. It would make sense for the service providers to invest in automation to use the least amount of engineering hours to keep the network humming along. In their use case, network automation is the key to their competitive advantage.

The difference between a service provider's network needs compared to a cloud data center is that, traditionally, service providers aggregate more services into a single device.

A good example would be Multiprotocol Label Switching MPLS that almost all major service providers provide but rarely adapt in the enterprise or data center networks. Juniper has identified this need and excelled at fulfilling the service provider requirements of automating. Juniper networks contributed heavily to both of the RFC standards. In fact, Juniper was the sole author for RFC On the Juniper device, you can always take a look at the configuration either in a flat file or in XML format.

The flat file comes in handy when you need to specify a one-liner command to make configuration changes:. Starting with ncclient 0. Start with some new imports for constructing new XML elements and the connection manager object:. Under the build configuration section, create a new element of system with subelements of host-namre and domain-name. If you were wondering about the hierarchy structure, you can see from the XML display that the node structure with system is the parent of host-name and domain-name:.

After the configuration is built, the script will push the configuration and commit the configuration changes.

These are the normal best practice steps lock, configure, unlock, commit for Juniper configuration changes:. This file can be executed by itself, or it can be imported to be used by other Python scripts.

Juniper also provides a Python library to be used with their devices called PyEZ. PyEZ is a high-level Python implementation that integrates better with your existing Python code. Juniper maintains a comprehensive Junos PyEZ developer guide on their technical library. If you are interested in using PyEZ, it ishighly recommended that you at least take a glance through the various topics in the guide.

The installation instructions for each of the operating systems can be found on the Installing Junos PyEZ page. Here are the installation instructions for Ubuntu For user authentication, you can either use password authentication or an SSH key pair. Creating the local user is straightforward:. Treat the private key like a password that you never share.You can deterministically control both the role and the member ID assigned to each member switch in an EX Virtual Chassis configuration by creating a preprovisioned configuration file.

A preprovisioned configuration file links the serial number of each EX switch in the configuration to a specified member ID and role.

The serial number must be specified in the configuration file for the member to be recognized as part of the Virtual Chassis configuration.

When you use a preprovisioned configuration, you cannot modify the mastership priority or member ID of member switches through the user interfaces. After you have created a preprovisioned Virtual Chassis configuration, you can use the autoprovisioning feature to add member switches to that configuration. This example describes how to configure a Virtual Chassis across multiple wiring closets using a preprovisioned configuration file:. Before you create the preprovisioned configuration of the Virtual Chassis and interconnect the members across the wiring closets, be sure you have:.

SWA-0 is going to be configured in the example to function as the master of the Virtual Chassis configuration. Thus, the properties that you specify for SWA-0 will apply to the entire Virtual Chassis configuration, including all the member switches that you specify in the preprovisioned configuration file.

You must select two members that you want to make eligible for election as master of the Virtual Chassis configuration. When you list these two members in the preprovisioned configuration file, you designate both members as routing-engine. One will function as the master of the Virtual Chassis configuration and the other will function as the backup.

You designate additional members, which are not eligible for election as master, as having the line-card role in the preprovisioned configuration file. This example shows how to create a preprovisioned configuration file on SWA-0 for all member switches that will be interconnected in the Virtual Chassis configuration.

The preprovisioned configuration file includes member IDs for the members in wiring closet A and for the members in wiring closet B. All other members are specified with the role of line-card.

If all member switches could be interconnected with their dedicated VCPs, you could simply power on the switches after saving and committing the preprovisioned configuration file.

The master detects the connection of the members through the dedicated VCPs and applies the parameters specified in the preprovisioned configuration file.

However, the Virtual Chassis cables that interconnect the VCPs of member switches within a single wiring closet are not long enough to connect member switches across wiring closets. Instead, you can configure the uplink module ports or the SFP networks ports on EXF switches as VCPs to interconnect the member switches in wiring closet A to the member switch in wiring closet B.

The uplink module ports that are not set as VCPs can be configured as trunk ports to connect to a distribution switch. Because this particular preprovisioned configuration is for a Virtual Chassis that is interconnected across wiring closets, we will bring up the Virtual Chassis configuration in stages. First, we power on SWA-0 without powering on any other switches and create the preprovisioned configuration file.

Then we power on the remaining switches in wiring closet A. If we check the status of the Virtual Chassis configuration at this point by using the show virtual-chassis command, it will display only member 0 through member 4. The members that have not yet been interconnected will not be listed. Without this setting, SWA-5 cannot be detected as a member switch by the master of the Virtual Chassis configuration. If you wish, you can run the EZSetup program and specify identification parameters.

When you interconnect SWA-5 with the master of the Virtual Chassis configuration, the master overwrites any conflicting parameters.

SWA-5 serial number pqr is specified as a routing-engine in the preprovisioned configuration file. If a problem occurred in wiring closet A, SWA-5 would take control of the Virtual Chassis configuration and maintain the network connections. Because SWA-0 is powered on prior to SWA-5, it has additional prioritization properties that cause it to be elected as master of the Virtual Chassis configuration.

The master can now detect that all members are present. Four XFP uplink modules. Two are installed in wiring closet A and two are installed in wiring closet B.

The rear view shows that the member switches within each wiring closet are interconnected to each other using the dedicated VCPs.
