As a best practice, disable remote ARP learning for VXLANs only when the controller and VTEPs are
synchronizing entries.
To disable remote ARP learning for VXLANs:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Disable remote ARP
learning for VXLANs.
vxlan tunnel arp-learning disable
By default, remote ARP learning is
enabled for VXLANs.

Unicast-mode VXLAN configuration example
Network requirements
As shown in Figure 7:
• Configure VXLAN 10 as a unicast-mode VXLAN on Switch A, Switch B, and Switch C to provide
Layer 2 connectivity for the user terminals across the network sites.
• Manually establish VXLAN tunnels and assign the tunnels to VXLAN 10.
• Enable remote-MAC address learning.
