Add one span for all BLSR or 1+1 portions of route from the source to the destination.
•
Add primary spans for BLSR-DRI (dual-ring interconnect) from the source to the destination
through the primary nodes, and then add spans through the secondary nodes as an alternative route.
shows an example of a manually routed BLSR-DRI circuit. The circuit map shows all
span types: unprotected, BLSR, and protection channel access (PCA). PCA spans can only be
chosen as part of the secondary path.
