Goal
In this tutorial we are going to to setup ESI-LAG (Ethernet Switch Identifier - Link Aggregation Group). According to Juniper: "ESI link aggregation groups (ESI-LAGs) enable one or more client devices to form a logical link aggregation group (LAG) interface with the peers".

- EVE-NG 2.0.3-112
- VQFX model: vqfx-10000 running JUNOS 19.4R1.10 for spines and leaves
