Intermediate System to Intermediate System (IS-IS) provides efficient
and reliable flooding of information to its peers; however, the
current flooding scopes are limited to either area scope or domain
scope. There are existing use cases where support of other flooding
scopes is desirable. This document defines new Protocol Data Units
(PDUs) that provide support for new flooding scopes as well as
additional space for advertising information targeted for the
currently supported flooding scopes. This document also defines
extended Type-Length-Values (TLVs) and sub-TLVs that are encoded
using 16-bit fields for Type and Length.
The protocol extensions defined in this document are not backwards
compatible with existing implementations and so must be deployed with
care.
This document is a product of the IS-IS for IP Internets Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
