RFC 3563 IETF - JTC1 Agreement on IS-IS July 2003
ISO/IEC/JTC1/SC6 is the JTC1 sub-committee which has responsibility
for maintenance of the IS-IS standard (ISO/IEC 10589).
The IS-IS Working Group of the IETF is chartered to develop
extensions to the IS-IS protocol to be used within the scope of the
Internet.
This addendum documents the agreed process for the future development
of IS-IS by both organizations.
2. Definitions
2.1 Core IS-IS Mechanisms
Core IS-IS Mechanisms are subsystems with associated algorithms, data
structures, and PDU formats as specified in (ISO/IEC 10589),
constituting the core of the IS-IS protocol and including the
following elements:
a) Framework of PDU formats, including TLVs defined in [10589]
b) Encapsulation of PDUs
c) Adjacency state machine and formation logic
d) DIS election algorithm
e) Initial LSP synchronization via CSNP exchange
f) Asynchronous LSP flooding (including DIS flooding behavior)
g) LSP database maintenance including LSP origination, aging, and
purging
h) Topology abstraction defined in [10589]
2.2 Internet-specific IS-IS Extensions:
Internet-specific IS-IS Extensions are extensions to the IS-IS
protocol that are within the work scope of the IETF including any
routing or packet forwarding technology that the IETF decides to work
on in the future (such as IPv4 or IPv6 unicast and multicast routing,
MPLS, MPLS Traffic Engineering, or Generalized MPLS), and:
a) do not modify the Core IS-IS Mechanisms and do not change
operation of non-IP or affect compatibility with non-IP and dual
implementations of IS-IS, or
