The following statement about static VXLAN tunnel configuration is correct?

NVE interface, and multiple VXLAN tunnels can create only one NVE interface

A BD needs to create an NVE country, and when there are multiple BDs, multiple NVE interfaces must be created

An NVE interface can be associated with multiple VNls, so you can create only one NVE interface when there are multiple BDs

For a VXLAN tunnel, you need to create a corresponding NVE interface, in which you explicitly specify the source IP address and the destination IP address , so there are multiple VXLAN tunnels on the VTEP that must be vE interfacesThe destination address of the VXLAN tunnel is specified in the

NVE interface, and multiple VXLAN tunnels can create only one NVE interface

The switch SWA and SWB are connected together by 2 Ethernet links, where the switch SWA has the following interface configuration:

Because of the different VLANs allowed, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 cannot join the same aggregation group
