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.
