How to Remove a Node From the UPSR
Now that Node4 has been successfully added to the UPSR ring, go through the procedures in order to remove
it. Add some circuits for demonstration purposes that drop at Node4 in order to start with some minor changes
to the current lab setup:
This procedure involves you to:
Delete circuits dropped at the node being removed.•
Initiate protection switches.•
Remove the node.•
Re−fiber the adjacent nodes.•
Delete and rebuild circuits that change STS or VT while they pass through the removed node.•
Delete Circuits Dropped at the Node Being Removed
Complete these steps in order to delete circuits dropped at the node being removed:
Identify and delete circuits dropped at Node4.
Caution: This step is service affecting. Ensure all traffic that dropped at this node has been
moved before you delete the circuits.
From the Network or Circuits view, identify any circuits that contain the node being removed (Node4)
in either the Source or Destination column. Click on the Source or Destination column heading in
order to sort columns.
