+# Leaf 1 configuration
+
+## Pre-config Setup
+
+Disable ZeroTouch provisioning :
+
+```config
+en
+zerotouch cancel
+```
+
+Enable the multi-agent configuration on Arista switch to be able to use EVPN feature
+
+```config
+en
+conf
+service routing protocols model multi-agent
+```
+
+Enabling IP Routing
+
+```config
+conf
+ip routing
+```
+
+## IP address Configuration
+
+Configure need to match with [Lab Topology](../../lab_vxlan.yml)
+
+```yml
+links:
+        - endpoints: ["spine1:eth1", "leaf1:eth1"]
+        - endpoints: ["spine1:eth2", "leaf2:eth1"]
+        - endpoints: ["leaf1:eth2", "host1:eth1"]
+        - endpoints: ["leaf2:eth2", "host2:eth1"]
+```
+
+That means :
+
+```config
+interface Ethernet1
+description TO_SPINE01
+no switchport
+ip address 10.1.1.1/31
+!
+interface Ethernet2
+description TO_HOST1
+switchport mode trunk
+!
+interface Loopback0
+description VTEP
+ip address 10.10.110.1/32
+!
+```
+
+## BGP Protocol
+
+```config
+router bgp 65101
+router-id 10.10.110.1
+maximum-paths 4 ecmp 4
+neighbor SPINE_GROUP peer group
+neighbor SPINE_GROUP allowas-in 1
+neighbor SPINE_GROUP ebgp-multihop 4
+neighbor SPINE_GROUP send-community extended
+neighbor SPINE_GROUP maximum-routes 12000
+neighbor 10.1.1.0 peer group SPINE_GROUP
+neighbor 10.1.1.0 remote-as 65001
+!
+address-family ipv4
+neighbor 10.1.1.0 activate
+```
+
+To check peer status :
+
+```cli
+show bgp summary
+```
+
+## BGP EVPN Overlay
+
+```config
+interface Loopback0
+description VTEP
+ip address 10.10.110.1/32
+!
+ip prefix-list VTEP_PREFIX seq 10 permit 10.10.110.1/32
+!
+route-map RMAP_VTEP permit 10
+match ip address prefix-list VTEP_PREFIX
+!
+router bgp 65101
+neighbor 10.10.110.2 peer group VTEP_GROUP
+neighbor 10.10.110.2 remote-as 65102
+neighbor 10.10.110.2 update-source Loopback0
+neighbor VTEP_GROUP peer group
+neighbor VTEP_GROUP ebgp-multihop 5
+neighbor VTEP_GROUP send-community extended
+!
+address-family evpn
+neighbor 10.10.110.2 activate
+!
+address-family ipv4
+no neighbor 10.10.110.2 activate
+redistribute connected route-map RMAP_VTEP
+```
+
+To check peer status :
+
+```cli
+show bgp summary
+show bgp evpn
+```
+
+## VXLAN IRB Configuration
+
+```config
+ip virtual-router mac-address 00:0a:bc:10:11:02
+!
+vlan 50
+name IRB_SERVICE
+!
+interface Vlan50
+description CUSTOMER01_ANYCAST_GW
+vrf CUSTOMER01
+ip address virtual 10.50.0.1/24
+!
+interface Vxlan1
+description VTI
+vxlan source-interface Loopback0
+vxlan vlan 50 vni 1050
+vxlan vlan 50 flood vtep 10.10.110.2
+!
+router bgp 65101
+!
+vlan 50
+rd 10.50.0.0:65101
+route-target both 10.50.0.0:1200
+redistribute learned
+```
+
+Now, hosts can ping each other, and ping to the VSI work too.
+
+```config
+show vxlan address-table
+```
