Using Juniper for the First Time | JunOS CLI

Using Juniper for the First Time | JunOS CLI
I have a mostly Cisco background, but it’s time to diversify. But the prospect of trying to use Juniper routers for the first time can be daunting.
If you’re in the same position, this video will help you. I’ve taken my initial Juniper learning and wrapped it up here to save you time, and help get you started.
We’ll look at operational mode and configuration mode, and how they’re different.
We’ll look at the candidate and active configurations, as well as deciphering how the configuration looks (it can be intimidating with curly braces and indents, but I promise it’s not hard at all!)
We’ll also look at configuring a few small items, and see how we can commit our changes once we’re happy.
We’re using Juniper’s vLabs throughout this video, which you can access for free:
jlabs.juniper.net/vlabs/

THANK YOU! This was even better than Juniper's "Learning Bytes". Your presentation is professional, instructive, and it just clicks well.

[@DaveLucre]

Please do more Juniper. A full configuration of an organisation with a data center, and multiple branch offices would be amazing.

I'll definitely be doing more Juniper. The topology you're suggesting sounds complicated... I'll need to figure out how to lab that.

Network Direction, automation, and programmability is at the heart of JUNOS, would definitely love to have a good series of JUNOS from a home network to the data center and automation ^^/ I really appreciate the great work and your content. Until the next JUNOS video.

[@noorur]

Very good video. I came here wanting to know how to use Jlabs, and got more than what I bargained for. You should definitely do another video for a more complex topology like OSPF or BGP, simply because a number of Cisco users may have difficulties navigating around the Jlabs, not the configuration part.

[@yousif91y]

very informative , thank you for the video

[@Vorcha2911]

Great start! I've been working with Juniper for over 5 years now. A nice command for production, is "Commit confirmed." This will commit the configuration but will rollback the configuration changes if you don;t enter another commit command. This definitely helps when doing remote configuration.

[@NetworkDirection]

That is a fantastic tip, thanks!

[@manuelaraica3216]

How much time do you have to do another commit command? Is there a timer or can you change the time?

I really love the 'commit confirmed' command on junos, it's much better than setting a 'reload in' time on a Cisco device and hoping you don't mess up since you'd have to wait not only for the reboot time, but however long you set for the reload timer.

[@YS_Production]

Junos CLI is awesome :) Any time I switched between Cisco and Juniper during the day I felt like Cisco CLI is a decade in the past.

[@YS_Production]

There are so many ways to manipulate the configuration and to display the configuration as well. I personally only used "show configuration | display set", and you can further modify it: "show configuration interfaces | display set | match disabled" - shows you all lines that contain disabled = you can identify all disabled interfaces - you see the whole conf. hierarchy on each line thanks to the display set option. I think there is no way to do this on a Cisco. And the video omits the best feature of the commit system - you can do commit confirmed to automatically roll back in case of not confirming the commit a second time. And the device stores a number of previous commits allowing you to do a manual roll back any time (days, weeks...).

[@NetworkDirection]

I agree! Especially the commit model. Juniper is a lot younger, and have the advantage that they were able to learn from other companies. More recently cisco released IOS-XR. I haven't used it, but from what I hear, it's more similar to Junos.

[@lforlilly8431]

Spot on mate

[@NetworkDirection]

[@SteveJones172pilot]

Great video.. SO MUCH better than another I just watched that was 3x longer and didn't have a tenth of the info in it.. Couple questions.. You showed that you can't have multiple subinterfaces on the loopback.. Can you have more than one loopback, each with an IP address, and if so, is that how you'd do layer 3 routing? If I wanted to basically have a dedicated layer 3 switch for a home lab, where the switch is trunked to a couple of VMWare servers, and I want the routing to happen in the switch, I can't figure out the best way to configure IP addresses for each VLAN without dedicating a specific port, and then I'm assuming if I did that, it wouldn't route to that VLAN if the port was down, so I'm wondering if each VLAN gets a loopback so that it remains up? Thanks!

[@luismejia857]

Awesome! Very informative. I'm familiar with pasting a config in cisco under config t. Is there a way to paste a config in junos?? Hmm 🤔

[@NetworkDirection]

There are two ways to do this. If you have the config in it's native form (with the curly braces), you can type 'load merge terminal', and then paste in your config. The other way is to get config as set commands. To do this, type 'show configuration | display set'. This will give you commands you can type straight in

For virtualized environments there's another option to use vQFX switches using Vagrant/VirtualBox - github.com/Juniper/vqfx10k-vagrant Although I've had little success in getting EVPN/VXLAN working using a virtual topology. I think it should be fine for learning configuration basics.

[@CommentingTheTruth]

I though junos had GUI available??

[@NetworkDirection]

That's a good point, yes it may However, it depends if it's enabled. For example, I always configure switches with the web console disabled to reduce the attack surface On the other hand, I leave it enabled on the SRX firewalls, but limit access to certain IP's. The thing is, you need to know the CLI, as you don't always have the GUI available. Troubleshooting on a console port is another example of this

[@CommentingTheTruth]

@@NetworkDirection I hear you. We just don't have any CCNA techs on prem and would like to be able to program the equipment ourselves without having to pay 3rd party IT support. We are considering moving away from Cisco to either Juniper Extreme or maybe Arista

[@NetworkDirection]

@@CommentingTheTruth in that case, yes! you can definitely use the web console. It still helps to understand the CLI concepts, as JWeb is based around that. For example, you still have commit and commit confirmed.

[@ElreyRayo]

aka the "Cisco-killer" or netter yet "resume maker.....

One thing I have noticed through all these years is that people who make a Cisco video, they make a Cisco video, Juniper isn't even mentioned. But every Juniper video feels like little children comparing themselves to the big guy Cisco. Even you do it "In Cisco that's like this and that". Why? Why must you compare Juniper to Cisco? Can't a Juniper video be made without these comparisons and so that like a tree Juniper can stand on its own? I don't make videos so maybe I don't get it. Imagine Burger King commercials comparing themselves to McDonald's constantly? Or the other way around? Great video though. I learned much. Juniper makes more sense than Cisco.

[@NetworkDirection]

That's a good point. The fact is, Cisco dominates the market, and are very well known. Most people who want to work with Juniper already have some experience with Cisco. Juniper even do this on their own site from time to time. It is good to consider Juniper for what it is, but we need to remember that it's easier to learn if we build on what we already have.

[@faisalak7]
