Abstract


   Key to the extensibility of the Intermediate System to Intermediate
   System (IS-IS) protocol has been the handling of unsupported and/or
   invalid Type/Length/Value (TLV) tuples.  Although there are explicit
   statements in existing specifications, deployment experience has
   shown that there are inconsistencies in the behavior when a TLV which
   is disallowed in a particular Protocol Data Unit (PDU) is received.

   This document discusses such cases and makes the correct behavior
   explicit in order to insure that interoperability is maximized.

   This document updates RFC5305 and RFC6232.
