Disable Tarp PDU Origination and Propagation

Chapter 9: AI2524 OSI/CLNP Configuration Steps

Disable TARP Caching

By default, TID-to-NSAP address mappings are stored in the TID cache. Disabling this capability clears the TID cache. Re-enabling this capability restores any previously cleared local entry and all static en- tries.

In global configuration mode, disable TID-to-NSAP address mapping in the TID cache:

no tarp allow-caching

Disable TARP PDU Origination and Propagation

By default, the router originates TARP PDUs and propagates TARP PDUs to its neighbors, and the interface propagates TARP PDUs to its neighbor. Disabling these capabilities means that the router no longer originates TARP PDUs. Also, the router and the specific interface no longer propagate TARP PDUs received from other routers.

zIn global configuration mode, disable origination of TARP PDUs: no tarp originate

zIn global configuration mode, disable global propagation of TARP PDUs.

no tarp global-propagate

zIn interface configuration mode, disable propagation of TARP PDUs on a specific interface:

no tarp propagate

Configure Multiple NSAP Addresses

A router may have more than one NSAP address. When a request for an NSAP is sent (Type 1 or Type 2 PDU), the first NSAP address is returned. To receive all NSAP addresses associated with the router, enter a TID-to-NSAP static route in the TID cache for each NSAP ad- dress.

In global configuration mode, create a TID-to-NSAP static route:

tarp map tid nsap

Configure Static TARP Adjacency and Blacklist Adjacency

In addition to all its IS-IS/ES-IS adjacencies, a TARP router propa- gates PDUs to all its static TARP adjacencies. If a router is not running TARP, the router discards TARP PDUs rather than propagating the PDUs to all its adjacencies. To allow TARP to bypass routers enroute
