Change Assigned Loopback IP Address (Datacenter)

Assign or change an individual loopback IP Address

Normally, IP addresses are pulled automatically from resource pools, but there may be times when you need to assign a specific IP address. In these cases, you can select the device and assign or change the IP address from the Properties tab.

To assign a specific loopback IP address using the GUI:

  1. From the blueprint, navigate to Staged > Physical > Topology and select the device to update. (Alternatively, you can navigate to Staged > Physical > Nodes and select the device from the Nodes table.)
    Network management interface showing physical topology with nodes like spine1, spine2, leaf nodes, and connected devices. Uncommitted changes are filtered, and a details panel prompts user interaction for more information.
    The Selection panel on the right becomes active and populates with information about the selection.
  2. Click the Properties tab in the Selection panel, then click the Edit button for the Loopback IP field.

Node properties: Name leaf3; Logical Device slicer-7x10-1; Interface Map Juniper_vQFX_slicer; Device Profile Juniper vQFX; ASN 64514; Loopback IP 10.0.0.2/32. Green checkmarks indicate correct configuration with uncommitted changes highlighted.
    The Loopback IP field becomes available to change.
  3. Enter the new Loopback IP address value.
  4. Click the Save button.
