DLP- F370 Remove a TARP Manual Adjacency Table Entry

Step 3 Click Create.

Step 4 In the Create IP Over OSI Tunnel dialog box, complete the following fields:

•Tunnel Type—Choose a 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 Open Shortest Path First (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 5 Click OK.

Step 6 Provision the other tunnel endpoint using the documentation for the other equipment. Step 7 Return to your originating procedure (NTP).

DLP-F370 Remove a TARP Manual Adjacency Table Entry

Purpose	This task removes an entry from the TARP manual adjacency table.
Tools/Equipment	None
Prerequisite procedures	DLP-F181 Log into CTC, page 16-34
Required/As needed	As needed
Onsite/Remote	Onsite or remote
Security Level	Provisioning or higher

Caution If TARP manual adjacency is the only means of communication to a group of nodes, loss of visibility will occur when the adjacency table entry is removed.

	Step 1 In node view, click the Provisioning > OSI > TARP > MAT tabs.
