9.6.9 OSI/IP Networking Scenarios

The following eight scenarios show examples of ONS 15600 SDHs in networks with OSI-based NEs.
The scenarios show ONS 15600 SDHs in a variety of roles. The scenarios assume the following:

ONS 15600 SDH NEs are configured as dual OSI and IP nodes with both IP and NSAP addresses.
They run both OSPF and OSI (IS-IS or ES-IS) routing protocols as "Ships-In-The-Night," with no
route redistribution.
ONS 15600 SDH NEs run TARP, which allows them to resolve a TL1 TID to a NSAP address. A
TID might resolve to both an IP and an NSAP address when the destination TID is an
ONS 15600 SDH NE that has both IP and NSAP address.
DCC links between ONS 15600 SDH NEs and OSI-only NEs run the full OSI stack over LAP-D,
which includes IS-IS, ES-IS, and TARP.
DCC links between ONS 15600 SDH NEs run the full OSI stack and IP (OSPF) over PPP.
