Hello @prohit,

On your leaf config I don't see interface loopback1. This is the source-interface under nve interface.... 

[prohit]

Sorry, I forgot to mention that.

interface loopback1
  ip address 100.1.1.1/32
  ip router ospf 1 area 0.0.0.0
  ip pim sparse-mode

M02@rt37 I am following this doc: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/92x/vxlan-92x/configuration/guide/b-cisco-nexus-9000-series-nx-os-vxlan-configuration-guide-92x/b_Cisco_Nexus_9000_Series_NX-OS_VXLAN_Configuration_Guide_9x_chapter_0100.html

It does not mentions loopback1 ip config on leaf. But i have configured.

OK @prohit 

On leaf config, why interface ethernet 1/1 is not is the ospf process called UNDERLAY ?

Put all physicals interfaces in the same OSPF process as underlay control plane.

I have updated update source of nve1 interface to loopback0 and that worked.
