#
Interface NVE [network virtualization endpoint] is the one on which we configure the VNI and multicast mapping
We cannot assign an IP address to this interface, hence we use a Loopback interfaces as its source-interface
#
#[which once assigned immediately creates a tunnel interface, the VTEP]
#The Loopback IP address should be reachable

The port being used by VXLAN can be viewed using the show command "show platform software vxlan F0 udp-port". The same is displayed below:

#
CSR1#show platform software vxlan F0 udp-port
VXLAN UDP Port: 4789

#
CSR1(config)#VXLan Udp port ?
<1024-65535> Port number

CSR1(config)#VXLan Udp port

#
If we fail to configure CSR2 with the same port, peer not up.
需要VTEP都修改成相同的UDP端口号，否则邻居无法建立；
