7.11 Manual Circuit Routing
CTC imposes the following rules on manual routes:
All circuits in a shared packet ring should have links with a direction that flows from source to
•
destination.
• If you enabled Fully Protected Path, choose a diverse protect (alternate) path for every unprotected
segment.
For a node that has an SNCP selector based on the links chosen, the input links to the SNCP selectors
•
cannot be 1+1 protected. The same rule applies at the SNCP bridge.
If you enabled Fully Protected Path, CTC verifies that the route selection is protected at all segments. A
route can have multiple protection domains with each domain protected by a different scheme.
