Unicast-mode VXLAN configuration example
Network requirements
As shown in Figure 8 :
• Configure VXLAN 10 as a unicast-mode VXLAN on Switch A, Switch B, and Switch C to provide
Layer 2 connectivity for the VMs across the network sites.
• Manually establish VXLAN tunnels and assign the tunnels to VXLAN 10.
• Use the default MAC address learning method (MAC address learning in the data plane).

Configuration procedure
1. Configure IP addresses and unicast routing settings:
# Assign IP addresses to interfaces, as shown in
Figure 8 . (Details not shown.)
# Configure OSPF on all transport network switches (Switches A through D). (Details not shown.)
2. Configure Switch A:
# Enable L2VPN.

[SwitchA] l2vpn enable
# Enable Layer 2 forwarding for all VXLANs.
[SwitchA] undo vxlan ip-forwarding
# Create the VSI vpna and VXLAN 10.
[SwitchA] vsi vpna
[SwitchA-vsi-vpna] vxlan 10
[SwitchA-vsi-vpna-vxlan10] quit
[SwitchA-vsi-vpna] quit
# Assign an IP address to Loopback 0. The IP address will be used as the source IP address of the
VXLAN tunnels to Switch B and Switch C.
