Step 8
Click Next.
Step 9 In the Circuit Source area, choose the node where the low-order tunnel will originate from the Node
drop-down list.
Step 10 Click Next.
Step 11 In the Circuit Destination area, choose the node where the low-order tunnel will terminate from the Node
drop-down list.
Step 12 Click Next.
Step 13 In the Circuit Routing Preferences area, choose Route Automatically. Two options are available;
choose 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
before the circuit is created.
Step 14 If you selected Using Required Nodes/Spans in Step 13:
a. Click Next.
b. In the Circuit Route Constraints For Auto Routing area, click a span on the low-order tunnel map.
c. Click Include to include the node or span in the low-order tunnel. Click Exclude to exclude the node
or span from the low-order tunnel. The order in which you choose included nodes and spans sets the
low-order tunnel sequence. Click spans twice to change the circuit direction.
d. Repeat Step c for each node or span that you wish to include or exclude.
e. Review the low-order tunnel route. To change the tunnel routing order, choose a node from the
Required 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 If you selected Review Route Before Creation in Step 13:
a. Click Next.
