Earlier in the lab, you modified a physical interface and also created a vPC interface. In this section, you will create a Loopback interface that will be eventually advertised into BGP from your external router in the next couple of sections.

Step 1 - Navigate to Interfaces & Launch Create Interface Wizard

Navigate to Interfaces to launch the Create Interface wizard:

1. Click Connectivity in the top navigation bar
2. Click Interfaces
3. Click Actions
4. Click Create Interface

Step 2 - Create a Loopback Interface

In the Create Interface wizard,

1. In the Type dropdown, click Loopback
2. In the Select a device dropdown menu, select Ext-Rtr
3. Set the Loopback ID to 0
4. Set the Interface VRF to BlueVRF
5. Set the Loopback IP to 172.16.1.1
6. Set the Interface Description to Ping Test Loopback
7. Click Save
8. Click Deploy
9. Click Deploy Config

Step 3 - Close Create Interface Wizard

1. In the top right corner, click the to close the Create Interface wizard

Step 4 - Review Loopback is Created

Back at the main Interfaces overview, confirm you see your Loopback0 created. This will be deployed to your Ext-Rtr for advertisement into BGP thus into the VXLAN EVPN fabric as an external route in subsequent sections.

Summary

You created a Loopback interface on the external router directly from Nexus Dashboard — no CLI session required. ND's interface management extends beyond VXLAN fabric switches to external devices, giving you a consistent workflow for all interface operations across your entire managed network.

Continue to the next section to create a BGP policy for a network statement that covers the Loopback you just created.
