DLP- D165 Provision OSI Routing Mode
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 SDH 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 > Main Setup
tabs.
Step 2
Choose a routing mode:
•
End System—The ONS 15454 SDH 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 SDH 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.
•
Intermediate System Level 1/Level 2—The ONS 15454 SDH performs IS functions. It
communicates with IS and ES nodes that reside within its OSI area. It also communicates with IS
L1/L2 nodes that reside in other OSI areas. Before choosing this option, verify the following:
–
The node is connected to another IS Level 1/Level 2 node that resides in a different OSI area.
–
The node is connected to all nodes within its area that are provisioned as IS L1/L2.
Step 3
If needed, change the LSP data buffers:
•
L1 LSP Buffer Size—Adjusts the Level 1 link state protocol data unit (PDU) buffer size. The default
is 512. It should not be changed.
•
L2 LSP Buffer Size—Adjusts the Level 2 link state PDU buffer size. The default is 512. It should
not be changed.
Step 4
Return to your originating procedure (NTP).
