Chapter 3 Turn Up a Node
DLP-G284 Provision the TARP Operating Parameters
•
Intermediate System Level 1/Level 2—The ONS 15454 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 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).
DLP-G284 Provision the TARP Operating Parameters
Step 1
In node view, click the
Provisioning > OSI > TARP > Config
tabs.
Step 2
Provision the following parameters, as needed:
•
TARP PDUs L1 Propagation—If checked (default), TARP Type 1 PDUs that are received by the
node and are not excluded by the LDB are propagated to other NEs within the Level 1 OSI area.
(Type 1 PDUs request a protocol address that matches a target identifier [TID] within a Level 1
routing area.) The propagation does not occur if the NE is the target of the Type 1 PDU, and PDUs
are not propagated to the NE from which the PDU was received.
Note
The TARP PDUs L1 Propagation parameter is not used when the Node Routing Area (on the
Provisioning > OSI > Main Setup tab) is set to End System.
•
TARP PDUs L2 Propagation—If checked (default), TARP Type 2 PDUs that are received by the
node and are not excluded by the LDB are propagated to other NEs within the Level 2 OSI areas.
(Type 2 PDUs request a protocol address that matches a TID within a Level 2 routing area.) The
propagation occurs if the NE is not the target of the Type 2 PDU, and PDUs are not propagated to
the NE from which the PDU was received.
Note
The TARP PDUs L2 Propagation parameter is only used when the Node Routing Area is
provisioned to Intermediate System Level 1/Level 2.
Purpose
This task provisions the TARP operating parameters including TARP
protocol data unit (PDU) propagation, timers, and loop detection buffer
(LDB).
