8.6.5.4 Manual TID to NSAP Provisioning
TIDs can be manually linked to NSAPs and added to the TDC. Static TDC entries are similar to static routes. For a specific TID, you force a specific NSAP. Resolution requests for that TID always return that NSAP. No TARP network propagation or instantaneous replies are involved. Static entries allow you to forward TL1 commands to NEs that do not support TARP. However, static TDC entries are not dynamically updated, so outdated entries are not removed after the TID or the NSAP changes on the target node.
8.6.6 OSI Virtual Routers
The ONS
>OSI > Routers tabs. The router has an editable manual area address and a unique NSAP System ID that is set to the node MAC address. The router can be enabled and connected to different OSI routing areas. The Router 1 manual area address and System ID create the NSAP address assigned to the node’s TID. Router 1 supports OSI TARP and tunneling functions. These include:
•TARP data cache
•
•LAN subnet
