Leaf 1 configuration

Pre-config Setup

Disable ZeroTouch provisioning :

Enable the multi-agent configuration on Arista switch to be able to use EVPN feature

Enabling IP Routing

IP address Configuration

Configure need to match with Lab Topology

links:
        - endpoints: ["spine1:eth1", "leaf1:eth1"]
        - endpoints: ["spine1:eth2", "leaf2:eth1"]
        - endpoints: ["leaf1:eth2", "host1:eth1"]
        - endpoints: ["leaf2:eth2", "host2:eth1"]

That means :

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
