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 th e specific in te rface 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, disabl e 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 no t running
TARP, the router discards TARP PDUs rather than propagating the
PDUs to all its adjacencies. To allow TARP to bypass routers enroute
