Configuring VLT for NSX-based VxLAN

After configuring NSX-based VxLAN on the device, configure VLT. To configure VLT for NSX-based VxLAN, follow these steps:

  1. Enable VLT on a switch, then configure a VLT domain and enter VLT-domain configuration mode.
    CONFIGURATION mode
    vlt domain domain-id
    The domain ID range is from 1 to 1000.
    Configure the same domain ID on the peer switch
  2. Configure the IP address of the management interface on the remote VLT peer to be used as the endpoint of the VLT backup link for sending out-of-band hello messages.
    VLT DOMAIN CONFIGURATION mode
    back-up destination ip-address
  3. Configure the port channel to be used as the VLT interconnect between VLT peers in the domain.
    VLT DOMAIN CONFIGURATION mode
    peer-link port-channel id-number
  4. Assign VLT system MAC address.
    VLT DOMAIN CONFIGURATION mode
    system-mac mac-address mac-address
  5. Enable peer routing.
    VLT DOMAIN CONFIGURATION mode
    peer-routing
  6. Configure the primary priority.
    VLT DOMAIN CONFIGURATION mode
    primary-priority value
    The priority values are from 1 to 65535. The default is 32768.
  7. Configure the unit ID.
    unit-id
    NOTE For controller-based VxLAN, the VLT unit ID is mandatory.
  8. Repeat these steps on the VLT peer switch.

VLT configuration:

DellEMC#show runn vlt
!
vlt domain 100
 peer-link port-channel 1
 back-up destination 38.0.0.1
 primary-priority 1
 system-mac mac-address 00:00:00:11:11:11
 unit-id 0
 peer-routing

Configuration on an interface that is not part of VLT (orphan port):

DellEMC#show run interface te 1/21
!
interface TenGigabitEthernet 1/21
1122 Virtual Extensible LAN (VXLAN)
vxlan-instance 1
no ip address
switchport
no shutdown
DellEMC#

Configuration on VLT port channel:

DellEMC#show run int po 10
!
interface Port-channel 10
 vxlan-instance 1
 no ip address
 switchport
 vlt-peer-lag port-channel 10
 no shutdown

The following are some of the show command outputs on the VLT primary:
