DLP- F370 Remove a TARP Manual Adjacency Table Entry
Step3 Click Create.
Step4 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.
Step5 Click OK.
Step6 Provision the other tunnel endpoint using the documentation for the other equipment.
Step7 Return to your originating procedure (NTP).
DLP-F370 Remove a TARP Manual Adjacency Table Entry
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.
Step1 In node view, click the Provisioning > OSI > TARP > MAT tabs.
Purpose This task removes an entry from the TARP manual adjacency table.
