DLP-G283 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
ES, IS Level 1, or 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 15454 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 LAP-D maximum transmission unit (MTU) size within the
OSI area.
Note For ONS 15454 nodes, three 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 In node view, click the Provisioning > OSI tabs.
Step 2 Choose a routing mode:
• End System—The ONS 15454 performs OSI end system (ES) functions and relies upon an
intermediate system (IS) for communication with nodes that reside within its OSI area.
Note The End System routing mode is not available if more than one virtual router is enabled.
• Intermediate System Level 1—The ONS 15454 performs OSI IS functions. It communicates with
IS and 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 OSI routing mode. Complete this task when the
ONS 15454 is connected to networks with third party NEs that use the OSI
protocol stack for DCN communication.
