13.7.8.4 IP-over-CLNS Tunnel Scenario 3: ONS Node to Router Across an OSI DCN
Figure 13-30 shows an IP-over-CLNS tunnel from an ONS node to a router across an OSI DCN. The
other vendor NE has an OSI connection to an IP DCN to which a CTC computer is attached. An OSI-only
(LAP-D) SDCC is created between the ONS NE 1 and the other vender GNE. The OSI over IP tunnel
can be either the Cisco IP tunnel or a GRE tunnel, depending on the tunnel types supported by the router.
