Example: VXLAN with a controller configuration

This example shows a simple NSX controller and an hardware OS10 VTEP deployed in VXLAN environment.

NSX controller implementation

To configure an NSX controller-provisioned VXLAN:

  • Configure the controller and the interfaces to be managed by the controller, in the OS10 VTEPs
  • Configure the NSX controller in VMware vCenter. For more information about configuring the NSX controller using the GUI, see the Configure and control VXLAN from the VMware vCenter.

You must configure an OS10 VTEP with the controller configuration so that the VTEP can communicate with the NSX controller. The NSX controller handles configurations and control plane operations in the VXLAN environment.

VTEP 1

  1. Configure the OSPF protocol in the underlay.

    OS10# configure terminal
OS10(config)# router ospf 1
OS10(config)# exit
OS10(config)# interface ethernet 1/1/55:1
OS10(config-if-eth1/1/55:1)# no switchport
OS10(config-if-eth1/1/55:1)# ip ospf 1 area 0.0.0.0
OS10(config-if-eth1/1/55:1)# exit

  2. Configure a Loopback interface.

    OS10(config)# interface loopback 1
OS10(config-if-lo-1)# no shutdown
OS10(config-if-lo-1)# ip address 200.0.0.1/32
OS10(config-if-lo-1)# exit

  3. Create an NVE instance and configure the Loopback interface as the VXLAN source tunnel interface.

    OS10(config)# nve
OS10(config-nve)# source-interface loopback 1

  4. Specify the NSX controller reachability information.

    OS10(config-nve)# controller ovsdb
OS10(config-nve-ovsdb)# ip 10.16.140.182 port 6640 ssl
OS10(config-nve-ovsdb)# max-backoff 10000
OS10(config-nve-ovsdb)# exit

  5. Assign interfaces to be managed by the controller.

    OS10(config)# interface ethernet 1/1/54:3
OS10(config-if-eth1/1/54:3)# switchport mode trunk
OS10(config-if-eth1/1/54:3)# no switchport access vlan
OS10(config-if-eth1/1/54:3)# nve-controller

  6. (Optional) Enable BFD.

    OS10(config)# bfd enable

VTEP 2

  1. Configure the OSPF protocol in the underlay.

    OS10# configure terminal
OS10(config)# router ospf 1
OS10(config)# exit
OS10(config)# interface ethernet 1/1/23:1
OS10(config-if-eth1/1/23:1)# no switchport
OS10(config-if-eth1/1/23:1)# ip ospf 1 area 0.0.0.0
OS10(config-if-eth1/1/23:1)# exit

  2. Configure a Loopback interface.

    OS10(config)# interface loopback 1
OS10(config-if-lo-1)# no shutdown
OS10(config-if-lo-1)# ip address 202.0.0.1/32
OS10(config-if-lo-1)# exit

  3. Create an NVE instance and configure a Loopback interface as the VXLAN source tunnel interface.

    OS10(config)# nve
OS10(config-nve)# source-interface loopback 1

  4. Specify the NSX controller reachability information.

    OS10(config-nve)# controller ovsdb
OS10(config-nve-ovsdb)# ip 10.16.140.182 port 6640 ssl
OS10(config-nve-ovsdb)# max-backoff 10000
OS10(config-nve-ovsdb)# exit

  5. Assign interfaces to be managed by the controller.

    OS10(config)# interface ethernet 1/1/25:3
OS10(config-if-eth1/1/25:3)# switchport mode trunk
OS10(config-if-eth1/1/25:3)# no switchport access vlan
OS10(config-if-eth1/1/25:3)# nve-controller

  6. (Optional) Enable BFD.

    OS10(config)# bfd enable

Verify the controller configuration

To view controller-based information on the VTEP 1, use the show nve controller command.

OS10# show nve controller
