Step7 Return to your originating procedure (NTP).
DLP-F361 Provision OSI Routing Mode
Caution 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.
Caution 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.
Caution 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.
Note 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.
Step1 Complete the “DLP-F181 Log into CTC” task on page16-34 at the node where you want to provision
the OSI routing mode. If you are already logged in, continue with Step 2.
Step2 In node view, click the Provisioning > OSI tabs.
Step3 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.
Purpose This task provisions the Open System Interconnection (OSI) routing mode.
Complete this task when the ONS 15600SDH is connected to networks
with third party network elements (NEs) that use the OSI protocol stack for
data communications network (DCN) communication.
