Existing traffic-engineering-related link attribute advertisements
have been defined and are used in RSVP-TE deployments. Since the
original RSVP-TE use case was defined, additional applications (e.g.,
Segment Routing Policy and Loop-Free Alternates) that also make use
of the link attribute advertisements have been defined. In cases
where multiple applications wish to make use of these link
attributes, the current advertisements do not support
application-specific values for a given attribute, nor do they
support indication of which applications are using the advertised
value for a given link. This document introduces new link attribute
advertisements that address both of these shortcomings.
This document is a product of the Link State Routing 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.
