A. To achieve Cisco Transport Controller (CTC) connectivity, interconnected Cisco ONS 15454 NEs use the SONET Data Communications Channel (SDCC) for communication. Communication is accomplished through a combination of the Open Shortest Path First (OSPF) routing protocol and manually-entered static routes. Static routes are required to be added in the Cisco ONS 15454 for specific IP network scenarios. For more information, refer to Chapter 11: IP Networking of the Cisco ONS 15454 Reference Manual, Release 5.0. See the examples given in user manuals. To add static routes, if required, go to the CTC Node view, and select Provisioning > Network > Static Route Create.
