DLP- F375 Delete an IP-Over-CLNS Tunnel

Caution Changing the IP or NSAP addresses or an IP-over-CLNS tunnel can cause loss of NE visibility or NE

isolation. Do not change network addresses until you verify the changes with your network administrator.

Step 1 Click the Provisioning > OSI > Tunnels tabs.

Step 2 Click Edit.

Step 3 In the Edit IP Over OSI Tunnel dialog box, complete the following fields:

•Tunnel Type—Edit the tunnel type:

–Cisco—Creates the proprietary Cisco IP tunnel. Cisco IP tunnels add the CLNS header to the IP packets.

–GRE—Creates a Generic Routing Encapsulation tunnel. GRE tunnels add the CLNS header and a GRE header to the IP packets.

The Cisco proprietary tunnel is slightly more efficient than the GRE tunnel because it does not add the GRE header to each IP packet. The two tunnel types are not compatible. Most Cisco routers support the Cisco IP tunnel, while only a few support both GRE and Cisco IP tunnels. You generally should create Cisco IP tunnels if you are tunneling between two Cisco routers or between a Cisco router and an ONS node.

Caution Always verify that the IP-over-CLNS tunnel type you choose is supported by the equipment at the other end of the tunnel.

•Node Address—Enter the IP address of the IP-over-CLNS tunnel destination.

•Subnet Mask—Enter the IP address subnet mask of the IP-over-CLNS destination.

•OSPF Cost—Enter the OSPF cost for sending packets across the IP-over-CLNS tunnel. The OSPF cost is used by OSPF routers to calculate the shortest path. The default is 110. Normally, it is not be changed unless you are creating multiple tunnel routes and want to prioritize routing by assigning different metrics.

•NSAP—Enter the destination NE or OSI router NSAP address.

Step 4 Click OK.

Step 5 Return to your originating procedure (NTP).
