Chapter 18 DLPs F300 to F399
DLP- F369 Create an IP-Over-CLNS Tunnel
Step 1 Complete the “DLP-F181 Log into CTC” task on page 16-34at the node whose OSI routers you want to provision.
Step 2 Click the Provisioning > OSI > Routers > Subnet tabs.
Step 3 Click Enable LAN Subnet.
Step 4 In the Enable LAN Subnet dialog box, complete the following fields:
•ESH—Sets the End System Hello (ESH) propagation frequency on ONS nodes that can be provisioned as end system NEs. The field is not used by the ONS 15600 SDH.
•ISH—Sets the Intermediate System Hello PDU propagation frequency. Intermediate system NEs send ISHs to other ESs and ISs to inform them about the IS NETs it serves. The default is
10 seconds. The range is 10 to 1000 seconds.
•IIH—Sets the Intermediate System to Intermediate System Hello PDU propagation frequency. The IS-IS Hello PDUs establish and maintain adjacencies between ISs. The default is 3 seconds. The range is 1 to 600 seconds.
•IS-IS Cost—Sets the cost for sending packets on the LAN subnet. The IS-IS protocol uses the cost to calculate the shortest routing path. The default IS-IS cost for LAN subnets is 20. It normally should not be changed.
•DIS Priority—Sets the designated intermediate system (DIS) priority. In IS-IS networks, one router is elected to serve as the DIS (LAN subnets only). Cisco router DIS priority is 64. For the
ONS 15454 LAN subnet, the default DIS priority is 63. It normally should not be changed.
Step 5 Click OK.
Step 6 Return to your originating procedure (NTP).
DLP-F369 Create an IP-Over-CLNS Tunnel
Purpose | This task creates an IP-over-Connectionless Network Layer Service |
| (CLNS) tunnel to allow ONS 15600 SDHs to communicate across |
| equipment and networks that use the OSI protocol stack. |
Tools/Equipment | None |
Prerequisite Procedures | NTP-F131 Verify Card Installation, page 4-2 |
Required/As Needed | As needed |
Onsite/Remote | Onsite or remote |
Security Level | Provisioning or higher |
Caution IP-over-CLNS tunnels require two endpoints. You will create one point on an ONS 15600 SDH. The other end point is generally provisioned on non-ONS equipment including routers and other vendor NEs. Before you begin, verify that you have the capability to create an OSI-over-IP tunnel on the other equipment location.
Step 1 Complete the “DLP-F181 Log into CTC” task on page 16-34at the node of the OSI routers that you want to provision.
Step 2 Click the Provisioning > OSI > Tunnels tabs.
