9.6.8 IP-over-CLNS Tunnels
9.6.8.4 IP-Over-CLNS Tunnel Scenario 3: ONS Node to Router Across an OSI DCN
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) 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 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
