Top products from r/Juniper

Hey u/mertino11,

To answer your questions:

1. Is there a fast track with Juniper since I've got my CCNP or do I have to begin from scratch? You would have to begin from scratch. Starting with the JNCIA (CCENT Level), JNCIS-ENT (CCNA Level), and JNCIP-ENT (CCNP Level).
   
2. What training methods do you guys use to get these certificates? CBTNuggets does not go into enough detail for the JNCIS-ENT and later exams. Juniper is known not to spoonfeed information. Ultimately, you will do a lot of research and or reading. I recommend purchasing the following three books; JUNOS Enterprise Switching: A Practical Guide to JUNOS Switches and Certification, Junos Enterprise Routing: A Practical Guide to Junos Routing and Certification, and The Unofficial JNCIE-ENT Prep Guide. You can also download a free Juniper Lab Workbook.
   
3. Are there virtual simulations with Juniper devices like in Cisco where they have Packet Tracer, GNS3, VIRL etc? Juniper does not offer anything like Packet Tracer. JUNOS will work with GNS3, but you will be responsible for obtaining the licenses. If your budget allows, I recommend getting real equipment.
   
4. Are all exams (besides Expert level) based on only MPC questions or also simlets / drag n drops etc? I recommend signing up for JUNOS Genius, it is free and provides several practice test.
   
5. And is there a criteria to pass? Like have 50 good / 65 questions? Juniper, like Cisco, does not release how they grade the exams.

I don't know of any OpenWRT-supported devices that have an SFP port, but I'm sure there's something out there.

The devices I currently use are all TP-Link WR710N and Trendnet TEW-714TRU, because both have built-in power plugs and you can just plug them into a receptical without a USB power adapter or other power adapter. Both are/were cheap at the $20-$30 price range. I don't actually recommend these models anymore because there's better. Also they have an obscure bug that causes the USB port to freak out and reset every once in awhile.

These are tiny low-end devices, but they work great for a serial port server. Each has a dinky 400Mhz CPU, 32MB of RAM and 8MB of flash storage. I custom-build the OpenWRT image so that I can build in picocom, tmux, and all the serial port drivers and other small tools I use.

I use these USB-to-serial adapters: https://www.amazon.com/TECHTOO-Professional-Adapter-Converter-Thumbscrews/dp/B06ZXRR5N7/

They say they are legit FTDI chips. All that I care about is that each port has a unique serial number that you can ID in the /sys filesystem. I wrote a script that associates the serial port ID to a host in a small file and you've got a menu system that you can log directly into and connect to each device with pre-configured settings like baud.

I should really do a project website on this. I can see this being really useful for other network engineers, but it's definitely daunting to look at because there's all these little parts of the system that have to go together.

The wikipedia pages are pretty good in my opinion:

https://en.m.wikipedia.org/wiki/Gigabit_Ethernet

https://en.m.wikipedia.org/wiki/10_Gigabit_Ethernet

https://en.m.wikipedia.org/wiki/Optical_fiber_connector

I just do single mode (with 10gig LR optics) everywhere now. For a while we did a lot of OM4 multi mode in the datacenter but in anything service provider or new buildout campus or datacenter I don't bother, even little stuff like MDU from an MDF to IDFs, single mode all day long (with LC termination).

I think most folks are going the same way.

I also strongly suggest (as another poster did) dropping a few bucks on cleaners and clean your stuff all the time.

Forget what I have turned on, followed pretty much what was in one of these books, can't remember which:

They are both pretty good reads for learning juniper stuff.
Good for best practices etc.

Old but still good. [Interdomain multicast] (https://www.amazon.com/Interdomain-Multicast-Routing-Practical-Solutions/dp/0201746123)

Same with the Soricelli guide

Also I would spend some time to sit down and read this NGN MVPN guide if you're planning on sitting down for your exam.

Juniper Enterprise Routing 2nd edition also has a good multicast section for reference.

for less than 100$ you have the o'reilly:
http://www.amazon.com/Junos-Enterprise-Routing-Practical-Certification/dp/1449398634 this one is mostly on EX series, but ospf, bgp, mutlicast, cos works almost the same on MX. Don''t find if there is one dedicated to service providers

That may work. I haven't used one like that personally.

I use something like this:

https://www.amazon.com/Plugable-Compatible-RS-232-DB9-Connector-Prolific/dp/B00425S1H8/ref=mp_s_a_1_16?keywords=usb+serial&qid=1574990295&sr=8-16

+

https://www.amazon.com/Cisco-72-3383-01-Rollover-Console-Female/dp/B005S2KPPU/ref=mp_s_a_1_15?keywords=cisco+console+cable&qid=1574990384&sprefix=cisco+co&sr=8-15


This gives you some flexibility to also use it with some network equipment that uses a db9 serial port instead of rj45

Never go mPim. Your router always manages to end up in the one spot with shoddy cell service.

Just get yourself a LTE bridge. You can put them anywhere on the property and nice ones have a POE lan connection for remotely powering the bridge.

Example:
https://www.amazon.com/NETGEAR-Modem-Gigabit-Ethernet-Ports/dp/B01MQRHQW4?th=1

I appreciate it guys, going to pick one up after the crazies are done black friday shopping.

Do I need to get a USB to db9 and db9 to rj45 or will this do - https://www.amazon.com/dp/B0769J9QXP/ref=cm_sw_r_tw_dp_U_x_s3g4DbW3HTKR2

I then suggest this book outside of fasttrack material

http://www.amazon.com/Junos-Enterprise-Switching-Harry-Reynolds/dp/059615397X

For these https://www.amazon.com/Cisco-1RU-Cable-Management-CABLEMGMT-1RU/dp/B00CLX4M4O

u/ricosiphone is right about the day one books. For tips and tricks, there are a couple of Day One Cookbooks on Juniper's site. You could also try the book from O'Reilly : https://www.amazon.com/JUNOS-Cookbook-Time-Saving-Techniques-Configuration/dp/0596100140

Thank you both. This is great info. An unknown for me is the RJ-45 to DB-9 adapter. I'm using a good RJ-45 (cat 5e I had lying around), and a usb-to-serial cable I had. To try and get connected I ordered a generic RJ-45 to DB-9 adapter. My guess is maybe the Juniper pinouts are different than what that generic one provides. I've now ordered a real JX-CONN-DB9 adapter.

I am really hoping the problem is my hardware I'm using to connect.

Again, thank you.

If that fails, it's time to bust out the multi meter :(

EDIT: I am thinking this is the problem. Looking at the pinout diagram of my generic adapter, and comparing it to the Juniper pinout, I think they are different. I'm finding a few different RJ-45 pin out diagrams online which is a little confusing.
