Hello,
I'm fairly new to Juniper (a few weeks since I started working with it) and I'm currently trying to manually configure a VXLAN tunnel between 2 EX4600 switches.
I started from the bottom, trying a basic configuration to see how it should be configured (used this tutorial: https://www.juniper.net/documentation/en_US/junos/topics/topic-map/vxlan-qfx-series.html#id-example-configuring-a-vxlan-layer-2-gateway), but sadly the vxlan tunnel between my switches doesn't come up. When I check everything that the tutorial says to look at to make sure the tunnel is working, nothing shows up, so the tunnel doesn't work (my configurations and outputs are at the end of this post).
I have read most of the forum posts regarding vxlan and all the tutorials possible, but nothing is helping. Can anyone, please, help me out and tell me what I do wrong or why isn't my tunnel coming up?
Thank you!
Best regards,
Alex

- Loopback interface (VTEP): lo0 - @10.2.2.2/32
- L2 interface: ge-0/0/20
Outputs:

I have nothing, no VTEP interface to direct to my vlan.
