How To Configure Routable VLAN Interfaces On Juniper (IRB Interfaces) 

Yeah, replace irb.xxx with vlan.xxx SRX 110 is still old software so no ELS support, so instead of IRB interfaces they use vlan. interfaces. Rest of the config should be the same, except it doesnt use interface-mode but port mode when setting access or trunk 👍

If the switch config has been deleted, then no. But if the switch is brand new and out of the box with the default config, it should have a default VLAN where all interfaces are part of. It depends on what version the switch ships with as I have found some of them have the interfaces pre-configured, and some of them dont.

Thank you! Cheers!

If you specify vlan.10 as the interface under vlans then you need to configure an interface vlan.10 under edit interfaces as well. The EX3300 uses IRB interfaces as well so just make everything irb.10 instead of vlan.10 and it should work.

Thanks! New videos will start again soon and on a regular basis

Thanks! Coming from Cisco I presume?

@@lameaveragetechies1040 Yes, I've done Cisco for the long time, and now I'm falling in love with Juniper. I have added 5 X SRX-240, 2 X EX3200 switches, 2 X 4200 switches stacked into a VC, and 1 X EX2200. I guess I serious about learning Juniper :)

Thanks for the kind words, appreciate it

Interesting, will test this out in my lab! Yeah sure, will setup a lab for Private VLAN and do a tutorial on that 👍

Yeah, you can configure up to 4095 IRB interfaces on most Junos devices

Thanks! We use EVE-NG for the labs.

Hi, currently we dont have our configs stored on any repositories, but we will be working on a Patreon model where these will be made available.

Thank you, much appreciated!

100% yeah!

Hi, ge- refers to 1gbps interfaces, and xe- refers to 10gbps interfaces. In our lab the QFX only has xe interfaces but if you connect it to a device with a 1gbps interface it will work. In practical deployments these interface speeds obviously need to be the same, but in the virtual lab it doesnt really matter

Might sound like a dumb question, but I've seen a network that uses IRBs to route traffic thru the entire network and I never understood it. is it because of the simplicity or is it cutting corners or because of a low budget for proper networking equipment? thank you!

@@dylanmorin8174 Hi, well, it depends on the design and the equipment used, but usually the WAN should have redundant links and for that you would use AE interfaces, not IRB. But you can also use IRB interfaces throughout if you need to share a physical link with multiple services, although there are better ways to do this than with IRB interfaces. In the ideal world you would have dedicated transit links, and those would use /30 or /31 addresses on the interfaces, and would be the only interfaces used for transit. But when you have multiple services using a single device / link then this might be used. Realistically you should only use IRB interfaces on switch interfaces that have multiple devices in the same bridge domain or VLAN, but on dedicated routers. TLDR: Yes, you technically can use it throughout your entire WAN, but there are better ways to do it, depending on the requirements and design.

@@lameaveragetechies1040 hm ive never heard of these AE interfaces. Maybe I don’t know enough of the anatomy of the network but from what I’ve seen it has core nodes that route traffic using irbs. Sorry if it sound’s confusing I’m still kind new to this job 😅

AE interfaces are aggregated ethernet, or LAG interfaces for redundancy, so instead of irb.x you’ll use ae0.x etc 👍

Do you want to send me your config to my email address in my info tab? Will have a look at it quickly and see if I spot anything. If you can include a simple drawing as well that will be great!

@@lameaveragetechies1040 Thanks again mate. Can"t wait for the Fortinet content.

Use vqfx 18 not 20.

do the following.. as these is issue with virtual labs. Drop into shell by using "start shell" Run "ps -aux | grep olive" Look at the PID for the process running olive-ultimate.elf Run "kill -9 This will reload the FPC and connectivity will work again.

What about it specifically is bad? I’ve had nothing but good feedback regarding this video so genuinely curious what you found bad about this video? Maybe it’s something we can improve on.

I'd suggest checking to see if RU-vid automatically set your resolution low, like 360p. These videos are actually pretty damn good TBH.
