Thank you all for reply!
@Sergiu.Daniluk In each of two VTEP(csr1000v), what I configured is 1. Multicast, 2. interface NVE, 3. service instance/encapsulation 4. bridge-domain to conbine NVI, interface and service-instance together. Sorry, the diagram should be like below. it has Core SW instead of VTEP3.
user-pc1 ------VTEP1 ------Core SW-----VTEP2------user-pc2
The below is relative VTEP1 config:

@RedNectar I am not sure the relation between VXLAN and ACI. but I think VXLAN is a important tunnel in ACI. If this is pure VXLAN structure, it should not be related with EPG and vrf, right?
I checked some documents. I feel we do not need to get involved with VXLAN too depth because ACI would take care of all complicated detail steps. Not sure if this is correct.
