Juniper EVPN-VXLAN configuration

Goal

In this tutorial we will setup a spine/leaf topology with 2 spines and 4 leaves. The goal is to configure EVPN-VXLAN

Prerequisites

For this tutorial I am using :

- EVE-NG 2.0.3-112

- VQFX model: vqfx-10000 running JUNOS 19.4R1.10

- spine1: ASN:65030

- spine2: ASN:65031

- leaf1: ASN:65032 in row A using 10.192.80.0/22 network

- leaf2: ASN:65033 in row B using 10.192.96.0/22 network

- leaf3: ASN:65034 in row C using 10.192.112.0/22 network

- leaf4: ASN:65035 in row D using 10.192.128.0/22 network

- 4 servers one in each row for testing communication

Setup and Configuration

Spine1 configuation

##basic configuration 
set system host-name spine1
## Edit policy-options
set policy-options policy-statement export-lo term lo0 from protocol direct
set policy-options policy-statement export-lo term lo0 from route-filter 10.0.1.13/32 exact
set policy-options policy-statement export-lo term lo0 then accept
set policy-options policy-statement lbpp term lb then load-balance per-packet
## #Seting the underlay network###
set protocols bgp group underlay authentication-key password1
set protocols bgp group underlay export export-lo
set protocols bgp group underlay multipath multiple-as
