4. In the Topology section of the page, right-click the device on the topology that you want to specify
as the LSP ingress, and then select Set as Ingress that appears. The device is set as the ingress of
the LSP and an icon S appears on the topology next to the device.
5. Right-click the device on the topology that you want to specify as the LSP egress, and then select Set
as Egress that appears. The device is set as the egress of the LSP and an icon D appears on the
topology next to the device.
6. Click Preview. The system automatically calculates the paths available for the LSP.
7. If more than one path are found available, the system displays them on the topology.
8. To specify the generated LSP to include or exclude a path, right-click the path and select Include or
Exclude, and then click Preview. The generated LSP is highlighted on the topology and all devices
on this LSP are displayed in the Path List section of the page.
9. In the Define LSP section of the page, enter the name for the LSP in the LSP Name field. The LSP
name can contain only letters, digits, and underscores.

Assigning values to outgoing labels
You can assign values to outgoing labels on devices along the LSP either manually or automatically.
To assign values to outgoing labels manually:
1. After the LSP path is configured, the path list displays the devices along the path in the Path List
section.
2. Click the Change Label Value icon in the Operation column of a device.
3. In the Change Label Value dialog box that appears, enter the value for the label. Make sure that
the outgoing label specified on a device is the same as the incoming label specified on the
downstream device. The ingress device has no incoming label. The value of a label must be an
integer. The minimum value is 16 and the maximum value is the maximum static label value
supported by device, which varies with device models.
4. Make sure that you have configured labels for all devices along the LSP. Click OK.
To assign values to outgoing labels automatically:
5. After the LSP path is configured, the path list displays the devices along the path in the Path List
section.
6. Click the Pre-Allocate Label button. Valid values are assigned to outgoing labels.
7. Click OK.
