13.7.8.3 IP-over-CLNS Tunnel Scenario 2: ONS Node to Router
Figure 13-29 shows an IP-over-CLNS tunnel from an ONS node to a router. The other vendor NE has an
OSI connection to a router on 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.
ONS NE 1 IP-over-CLNS tunnel provisioning:
• Destination: 10.10.30.10 (Router 1, Interface 0/1)
• Mask: 255.255.255.255 for host route (Router 1 only), or 255.255.255.0 for subnet route (all routers
on the same subnet)
• NSAP: 39.840F.80.1111.0000.1111.1111.bbbbbbbbbbbb.00 (Router 1)
• Metric: 110
• Tunnel Type: Cisco IP
