DLP- A535 Provision or Modify 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.
Step4 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.
Step5 Return to your originating procedure (NTP).
DLP-A535 Provision or Modify TARP Operating Parameters
Step1 In node view, click the Provisioning > OSI > TARP > Config tabs.
Step2 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 Level1 OSI area.
(Type1 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 Type1 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
(Provisioning > OSI > Main Setup tab) is set to End System.
TARP PDUs L2 Propagation—If checked (default), TARP Type 2 PDUs received by the node that
are not excluded by the LDB are propagated to other NEs within the Level 2 OSI areas. (Type2
PDUs request a protocol address that matches a TID within a Level2 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 Level1/Level 2.
Purpose This task provisions or modifies the Target Identifier Address Resolution
Protocol (TARP) operating parameters including TARP protocol data unit
(PDU) propagation, timers, and loop detection buffer (LDB).
