8.6.7.4 IP-Over-CLNS Tunnel Scenario 3: ONS Node to Router Across an OSI DCN

Figure 8-21shows 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) RS-DCC 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.

IP-over-CLNS tunnel provisioning on ONS NE 1:

•Destination: Router 2 IP address

•Mask: 255.255.255.255 for host route (CTC 1 only), or 255.255.255.0 for subnet route (all CTC computers on the same subnet)

•NSAP: Other vender GNE NSAP address

•Metric: 110

•Tunnel Type: Cisco IP

IP-over-OSI tunnel provisioning on Router 2 (sample Cisco IOS provisioning):
