Configure Trunks and Access Ports on Juniper Devices

This video is a demonstration of how to configure trunk and access ports on the different Junos platforms (MX/QFX/EX/SRX).

Attached below is a link to Junipers official documentation for how to configure VLANs and Trunking on EX & QFX series platforms.

Quick question, can you combine both the interface-mode command and the vlan members into 1 set command?
IE: set interfaces ge-0/0/0 unit 0 family ethernet-switching interface-mode access vlan members VLAN2-LAN
vs 2 separate commands of:
set interfaces ge-0/0/0 unit 0 family ethernet-switching interface-mode access
and then
set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members VLAN2-LAN

hey (newbie here), your demonstration shows you configured a trunk vlan across the vMX to qFX, would it still been possible the same interfaces had a static route already setup? I

Fantastic instruction Jon. I have a question, I am tasked with setting up a high availability firewall and with only one WAN I wanted to create 3 ports on Juniper switch that allows the 2 WANS from the firewalls to plug into the Juniper along with the actual ISP WAN. Based on your videos I have created VLAN on 3 ports, that is completed, the configuration I was referencing they setup a different manufacturers switch and what they did on their switch is add Ingress filtering to those 3 vlanned ports. How is this completed on a Juniper, I can't really find any information on this. Any idea, thanks.

hi thanks for this lab, is it working if we use mx-mx ?

[err]

why do you use .0 and not .10? ( g0/0/3.0 ) ? tnx

may i know, what the app used to make a topoloy?

Hello friend!
I know two other ways to configure the vlan trunk, however, I would like to know what the differences are between them?

1. set interfaces ge-0/0/1 vlan-tagging encapsulation extended-vlan-bridge unit 0 vlan-id 100
set bridge-domains vMX interface ge-0/0/1.0
2. set interfaces ge-0/0/1 encapsulation ethernet-bridge unit 0
set bridge-domains vMX vlan-id 100 interface ge-0/0/1.0

Here was your configuration that I learned:
3. set interfaces ge-0/0/1.0 family bridge interface-mode trunk vlan-id-list 100
set bridge-domains vMX vlan-id 100

Thanks!

Hi boss, can I have image for eve-ng?

Why can't we configure the "trunk" mode on the physical interface "xe-0/0/0"... Why is it defined on a logical interface within?
What is the mode of the physical interface if you define an access or trunk mode on a logical (sub) -interface?

Now, I do understand to assign a VLAN to subinterface of any given trunk port, since every VLAN has it's own broadcatsdomain.
But since the VLAN assignment on the logical subinterface is hierarchically under the trunk port setting, it is quite confusing when a trunk mode is already set on a subinterface.
This is confusing. That would imply that since the logical subinterface is in trunk mode and trunks can hold multiple VLANs, VLANs should be assigned to another logical deeper level....
And this becomes absurd ofcourse...
