Thanks for the reply. Pls find the details of get interfaces....
On the other end (router), i did the debug, actually, it is establishing TCP connection and the other end, sends the BGP-OPEN message, then NSX sends TCP reset message...
Other end (router) is trying to establishing the TCP and sending BGP OPEN message, but NSX-T send TCP reset message, and not sending any BGP OPEN message...
its is like there is not BGP configured on NSX-T tire-0 gateway... On tire-0 it shows as "Administratively shutdown" , even with BGP enabled on UI...
On NSX-T, Snippet of the uplink interface, where BGP connection trying to establish:
