IP-Over-CLNS Tunnel Scenario 3: ONS Node to Router Across an OSI DCN
9.7.9 OSI/IP Networking Scenarios
The following eight scenarios show examples of ONS 15600s in networks with OSI-based NEs. The
scenarios show ONS 15600s in a variety of roles. The scenarios assume the following:
•
ONS 15600 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 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 NE
that has both IP and NSAP address.
•
DCC links between ONS 15600 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 NEs run the full OSI stack and IP (OSPF) over PPP.
