NSX Lab topology
We do have one VXLAN environment with some VMs and two VTEP Gateways.
Those gateways has connected to them two physical routers completely independent that belongs to the same tenant.

Switch vxlan configuration at VTEP - 1
• At each switch we have to configure the vxlan-instance and to enable the vxlan feature

Let’s going to add those VTEP to the Tenant in
order to permit the connectivity
• We have to start again from the Service definition in order to add the virtual switches to VTEP Hardware
• Please remember that but VLAN all fields are selectable clicking at “change” and “select”, preventing any mistake

CASOS de USO, preguntas abiertas
• La red es algo que no controlo, cómo puedo hacerla fácil?
• Seguridad?, realmente aporta SDN un plus de seguridad?
• Ruido en la red… broadcast y demás
• Todas las vlanes en todos los puertos?
• Y para entornos SDS? O BigDATA?
• Qué pasa en la red quién me dice algo?
• BONUS: Y para el campus qué?
