NTP- D187 Create a Low-Order Aggregation Point
Click Next.
Step 10
In the Circuit Destination area, choose the node where the low-order circuits aggregated by the LAP will
Step 11
terminate from the Node drop-down list.
Click Next.
Step 12
In the Circuit Routing Preferences area, choose Route Automatically. Two options are available; choose
Step 13
either, both, or none based on your preferences.
• Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or
exclude in the CTC-generated tunnel route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path
of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans
are not in the working or protect path of the circuit.
Review Route Before Creation—Check this check box to review and edit the low-order tunnel route

Click Next.
a.
In the Circuit Route Constraints For Auto Routing area, click a span on the LAP map.
b.
Click Include to include the node or span in the LAP. Click Exclude to exclude the node or span
c.
from the LAP. The sequence in which you choose the nodes and spans sets the LAP sequence. Click
spans twice to change the circuit direction.
Repeat Step
d.
Review the LAP route. To change the tunnel routing order, choose a node from the Required
e.
Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the tunnel
routing order. Click Remove to remove a node or span.

Step 15
Click Next.
a.
Review the tunnel route. To add or delete a tunnel span, choose a node on the tunnel route. Blue
b.
arrows show the tunnel route. Green arrows indicate spans that you can add. Click a span arrowhead,
then click Include to include the span or Remove to remove the span.
If the provisioned tunnel does not reflect the routing and configuration you want, click Back to
c.
verify and change the tunnel information.
Step 16 Click Finish. The Circuits window appears.
Step 17 Verify that the LAP you just created appears in the circuits list. LAPs are identified in the Type column.
Stop. You have completed this procedure.
