OVSDB VTEP with NSX Configuration
- Tracy Yang
Requirements
This example uses the following hardware and software components:
- A Trident-II Series switch
- PicOS (more than 2.6 version)
- NSX controller
Overview
In this example, OVSDB VTEP is configured to run on a VXLAN domain. VTEP interfaces sources are configured to the loopback address. Interfaces are configured for VLAN tagging and encapsulation. Static route protocols are configured to facilitate unicast routing.
Topology
The VXLAN networks Host and VM IP address and Mac address information :
Host IP Address: 172.168.1.1, Mac address: 70:72:cf:9d:6f:fb
VM1 IP Address: 172.168.1.2, Mac address: 00:50:56:ae:46:d3
VM1 IP Address: 172.168.1.3, Mac address: 00:50:56:ae:5a:30
Configuring OVSDB on Trident-II Series Switches
CLI Quick Configuration
To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and copy and paste the commands into the CLI.

Configuring OVSDB Step-by-Step Procedure
The following example shows how to set up a basic VTEP OVSDB configuration with VXLAN domain. To configure VXLAN on an Trident-II Series switches, follow these steps:
Configure OVSDB Step-by-Step for SW1
Configure the VLAN ID to 10 for vxlan domain.
set vlans vlan-id 100
Configure the VLAN ID to 1000 for ip routing.
set vlans vlan-id 1000 l3-interface vlan-1000
Configure the te-1/1/9 interface VLAN ID to 1000.
set interface gigabit-ethernet te-1/1/9 family ethernet-switching native-vlan-id 1000
Configure VLAN trunk for te-1/1/31.
set interface gigabit-ethernet te-1/1/31 family ethernet-switching port-mode "trunk"
Configure the te-1/1/31 interface VLAN ID to 100.
set interface gigabit-ethernet te-1/1/31 family ethernet-switching vlan members 100
Configure IP address for the vlan-interface vlan-1000.
set l3-interface vlan-interface vlan-1000 address 192.168.50.157 prefix-length 24
Configure VTEP interface sources IP address.
set vxlans source-interface vlan-1000 address 192.168.50.157
Enable VXLAN managed by ovsdb
set vxlan ovsdb-managed true
Configure ovsdb controller ip address
set protocols ovsdb controller ovsdb address 10.10.50.212
Configure ovsdb controller protocol
set protocols ovsdb controller ovsdb protocol ssl
Configure ovsdb controller port
set protocols ovsdb controller ovsdb port 6632
Configure ovsdb the interface on the VTEP
set protocols ovsdb interface te-1/1/31
Manually configuring the Switch as a VTEP Gateway by NSX Manager
Configuring the ovsdb by NSX Manager for SW1
- Add components in NSX manager.
- Add ESXi in NSX Manager
- Add hardware gateway
- Create Transport Zone
- Create Logical switch
- Create Logical port
- Add gateway VTEP port
