To configure a loopback interface do the following:

From the NSX-T Manager web interface, go to Networking >> Tier-0 Gateways and expand the target Tier-0 gateway.

Expand interfaces and click "Add Interface".

Enter a name, select "Loopback" as the Type, enter an IP address, select an Edge Node for the interface, and then click "Save".

Note: More than one loopback may need to be configured depending on the routing architecture.

To set the source address for BGP neighbors do the following:

From the NSX-T Manager web interface, go to Networking >> Tier-0 Gateways >> expand the target Tier-0 gateway.

Expand BGP >> next to BGP Neighbors click on the number present to open the dialog >> select Edit on the target BGP Neighbor.

Under Source Addresses configure the source address with the loopback address and click Save.
