If the diagram is correct, there is no L2 loop. If you're experiencing a broadcast storm then my guess is that someone has inadvertently physically bridged vlan1 and vlan2 somewhere with a cable. You can try and track it down, or deploy spanning-tree in your environment to mitigate the loop.

Subject: Network loop with 2 Vlans Junos 2300
Hello. We have a problem with Junos Ex2300. I attached an image to make it easier to understand. We have made several Vlans on the switch, but when we connect Vlan1 to a switch and vlan2 to another switch that are connected to each other, it creates a network loop, I don't know if I have to configure something that I don't know or it should work with the configuration that we have and what is wrong is the hardware of the device. Sorry for my English. I use google translate.
