In this blog how we will discuss how to integrate Bare metal devices with Juniper Contrail (SDN Controller) by using EVPN-VXLAN.
My earlier blogs on Contrail can be viewed on links Blog-1, Blog-2 ,
Reference Topology
Problem statement “Gust VM spawned inside SDN environment needs to communicate with Bare Metal Device (same sub net or different sub net here we will discuss former use case only).

Solution components:-
- Contrail GUI
- RED network 2.2.2.0/ is configured and VMs are spawned using open stack “Horizon” Web GUI (not covered in this article)
- Configure VxLAN as 1st encapsulation method under “Encapsulation Priority Order” go to Configure then Infrastructure then Global Config and click edit button.
- Select VxLAN Identifier Mode as “user configured”
- Configure VxLAN ID & Route target community for the desired network
- Go to Configure then Networking then Networks, select the desired network and click edit
