5.3.3 Adding and Removing UPSR Nodes

This section explains how to add and remove nodes in an ONS 15454 UPSR configuration. To add or
remove a node, you switch traffic on the affected spans to route traffic away from the area of the ring
where service will be performed. Use the span selector switch option to switch traffic from a UPSR span
at different protection levels. The span selector switch option is useful when you need to reroute traffic
from a UPSR span temporarily to add or drop nodes, perform maintenance, or perform other operations.
