Cisco ONS 15454 Procedure Guide, R5.0
August 2005
Chapter 6 Create Circuits and VT Tunnels
NTP-A314 Create a Unidirectional OC-N Circuit with Multiple Drops
Note
For manually routed circuits, CTC checks your manually provisioned path against the path
diversity option you choose. If the path does not meet the path diversity requirement that is
specified, CTC displays an error message.
Step 14
If you selected Fully Protected Path in
and the circuit will be routed on a BLSR DRI or
path protection DRI, check the
Dual Ring Interconnect
check box.
Step 15
Click
Next
. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If
you checked Dual Ring Interconnect for BLSR, continue with
. If you did not check Dual Ring
Interconnect, continue with
.
a.
Click a node or span on the circuit map.
b.
Click
Include
to include the node or span in the circuit. Click
Exclude
to exclude the node or span
from the circuit. The order in which you choose included nodes and spans is the order in which the
circuit is routed. Click spans twice to change the circuit direction.
c.
Repeat Steps a and b for each node or span you wish to include or exclude.
d.
Review the circuit constraints. To change the circuit routing order, choose a node in the
Required Nodes/Lines or Excluded Nodes Links lists and click the
Up
or
Down
buttons to change
the circuit routing order. Click
Remove
to remove a node or span.
Step 16
If you checked Dual Ring Interconnect in
for a BLSR DRI, complete the following substeps to
assign primary and secondary nodes. Otherwise, continue with
a.
In the Route/Review Edit area, click the
BLSR-DRI Nodes
tab.
b.
Click
Add BLSR DRI
.
c.
In the Node Options area of the BLSR DRI Options dialog box, complete the following (for an
example of a traditional and integrated route on primary and secondary nodes, see
):
•
Primary Node—For a traditional or integrated BLSR-DRI, choose the node where the circuit
interconnects the rings.
•
Secondary Node—For a traditional or integrated BLSR-DRI, choose the secondary node for the
circuit to interconnect the rings. This route is used if the route on the primary node fails.
•
Primary Node #2—For a traditional BLSR-DRI where two primary nodes are required to
interconnect rings, choose the second primary node.
•
Secondary Node #2—For a traditional BLSR-DRI where two secondary nodes are required,
choose the second secondary node.
d.
In the Ring and Path Options area, complete the following:
•
The first ring is—Choose UPSR or BLSR from the drop-down list.
•
The second ring is—Choose UPSR or BLSR from the drop-down list.
•
Use ring interworking protection (RIP) on secondary path—Check this box to carry the
secondary spans on the protection channels. These spans will be preempted during a ring/span
switch.
e.
Click
OK
.
f.
Review the circuit constraints. To change the circuit routing order, choose a node in the
Required Nodes/Lines lists and click the
Up
or
Down
buttons to change the circuit routing order.
Click
Remove
to remove a node or span.
g.
Click the
Included Spans
tab, and continue with
