Nexus 9000v vxlan evpn

Hi. 

Does VXLAN EVPN inter-vxlan routing work in data plane on Nexus 9000v? I followed steps documented, but the ping messages don't pass between vxlans. Intra-vxlan traffic has no issue.

There are just vxlan type-2 routes inside BGP EVPN table, but no any type-5. Why isn't there any type-5 routes?

here is my shared configs of VTEPs (nexus 9000v (nxos.7.0.3.I7.2)):

intra-vxlan traffic is fine. but between vxlans, isn't. 

Any Idea guys? Isn't there anyone who has worked with VXLAN on Nexus throughout the Data Center forum on Cisco?!!

I found the answer by myself. Thought I could get my answers here but it seems no one cares. 

Can you at least share what you did to fix it? 

Hi;
Please refer to the post that I wrote about this in more details. http://www.tcpuniverse.com/cisco/deploying-vxlan-with-cisco-nexus-9000v-part-1/

This url is not reachable

Did you ever resolve this? I am trying to build a Spine Leaf architecture as well and am looking for some help.

Hey I just say this and I care bro :)

I am looking for some help with building Spine Leaf architecture.

hi,

can you share what was missing in your config? It looks fine to me.
