Figure 168. Controller-based VXLAN for VLT Providing Redundancy
Important Points to Remember
• The VLT peer port channel number must be the same on both VLT peers.
• before conguring controller-based VXLAN with VLT, remove any existing standalone VXLAN conguration.
• BFD tunnels come up only after the NSX controller sends tunnel details. The details come after the remote MAC addresses are
downloaded from NSX controller.
Congure NSX Controller-based VxLAN in VLT Setup
You can congure NSX controller-based VxLAN in a VLT setup. To congure NSX controller-based VxLAN in a VLT setup, perform the
following tasks:
1 (Optional) Congure BFD and UFD. For more details on how to congure BFD and UFD for NSX controller-based VxLAN in VLT a
setup, Conguring BFD and UFD section.
2 Congure VxLAN on VLT peer devices. For more details on how to congure VxLAN for VLT, see the Conguring NSX-based VxLAN
on VLT Peer Devices section.
3 Congure VLT on VLT peer devices for VxLAN. For more details on how to congure VLT for VxLAN, see the Conguring VLT for
NSX-based VxLAN section.
4 Congure the NSX controller. For more details on conguring the NSX controller, see the Conguring and Controlling VXLAN from the
NSX Controller GUI section.
