10.12 Manual Circuit Routing
Figure 10-10 Ethernet and SNCP
•
Low-order tunnels cannot be the endpoint of an SNCP segment. A SNCP segment endpoint is where
the SNCP selector resides.
If you provision full path protection, 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.
Table 10-8 through Table 10-11 on page 10-21 summarize the available node connections. Any other
combination is invalid and generates an error.
