Note

Purpose	This task provisions the Open System Interconnection (OSI) routing mode.
	Complete this task when the ONS 15600 SDH is connected to networks
	with third party network elements (NEs) that use the OSI protocol stack for
	data communications network (DCN) communication.
Tools/Equipment	None
Prerequisite Procedures	NTP-F131 Verify Card Installation, page 4-2
Required/As Needed	As needed
Onsite/Remote	Onsite
Security Level	Provisioning or higher

Do not complete this task until you confirm the role of the node within the network. It will be either an Intermediated System (IS) Level 1 or an IS Level 1/Level 2. This decision must be carefully considered. For additional information about OSI provisioning, refer to the “Management Network Connectivity” chapter of the Cisco ONS 15600 SDH Reference Manual.

Link State Protocol (LSP) buffers must be the same at all NEs within the network, or loss of visibility might occur. Do not modify the LSP buffers unless you confirm that all NEs within the OSI have the same buffer size.

LSP buffer sizes cannot be greater than the Link Access Protocol on the D Channel (LAP-D) maximum transmission unit (MTU) size within the OSI area.

For ONS 15600 SDHs, twelve virtual routers can be provisioned. The node primary Network Service Access Point (NSAP) address is also the Router 1 primary manual area address. To edit the primary NSAP, you must edit the Router 1 primary manual area address. After you enable Router 1 on the Routers subtab, the Change Primary Area Address button is available to edit the address.

Step 1 Complete the “DLP-F181 Log into CTC” task on page 16-34at the node where you want to provision the OSI routing mode. If you are already logged in, continue with Step 2.

Step 2 In node view, click the Provisioning > OSI tabs.

Step 3 Choose a routing mode:

•Intermediate System Level 1—The ONS 15600 SDH performs OSI IS functions. It communicates with IS and End System (ES) nodes that reside within its OSI area. It depends upon an IS L1/L2 node to communicate with IS and ES nodes that reside outside its OSI area.
