BGP trigger Segment Routing ODN
This document defines an extension to the BGP SR Policy NLRI
(draft-ietf-idr-segment-routing-te-policy) in order to use BGP to trigger
Segment Routing ODN, without using PCEP.
The goal is to consolidate the SR Policy provision(BGP-TE), collection(BGP-LS)
and ODN-trigger protocol for device to be BGP only, thus remove the need
for PCEP and reduce the network complexity and potential bugs cause by
different protocol interactions.

7. Implementation Status
Note to RFC Editor: Please remove this section prior to publication,
as well as the reference to RFC 7942.
This section records the status of known implementations of the
protocol defined by this specification at the time of posting of this
Internet-Draft, and is based on a proposal described in [RFC7942].
The description of implementations in this section is intended to
assist the IETF in its decision processes in progressing drafts to
RFCs. Please note that the listing of any individual implementation
here does not imply endorsement by the IETF. Furthermore, no effort
has been spent to verify the information presented here that was
supplied by IETF contributors. This is not intended as, and must not
be construed to be, a catalog of available implementations or their
features. Readers are advised to note that other implementations may
According to [RFC7942], "this will allow reviewers and working groups
to assign due consideration to documents that have the benefit of
running code, which may serve as evidence of valuable experimentation
and feedback that have made the implemented protocols more mature.
It is up to the individual working groups to use this information as
they see fit".
When IANA-assigned values are available, implementations will be
updated to use them.
