Technical Summary
This document specifies extensions to Resource Reservation Protocol-
Traffic Engineering (RSVP-TE) to support Lock Instruct (LI) and
Loopback (LB) mechanisms for Label Switched Paths (LSPs). These
mechanisms are applicable to technologies which use Generalized
Multi-Protocol Label Switching (GMPLS) for the control plane.
Working Group Summary
This document moved from the CCAMP to TEAS WGs as part of
the routing WG changes. This document has been fairly
noncontroversial.
Document Quality
The base GMPLS protocol has been implemented. The extensions
defined in this document are compatible with earlier implementations
and satisfy requirements previously documented in RFCs. While
there have been no public statements on implementation, the
authors are from multiple vendors and an operator, and
implementation is expected.
Personnel
Lou Berger is the Document Shepherd
Adrian Farrel is the Responsible Area Director
RFC Editor Note
s3.2, para 2:
OLD:
The ingress node MUST ensure that the entity (node or interface), at
which loopback is intended to occur, is marked as a strict hop in the
Explicit Route Object (ERO) subobject.
NEW:
The ingress node MUST ensure that the entity at which loopback is
intended to occur is explicitly identified by the immediately
preceding subobject of the ERO Hop Attributes subobject.
END
s3.2, para 3,
AFTER
Otherwise, the node SHOULD try to put the LSP into loopback mode.
ADD
The loopback SHOULD be enabled on the entity identified by the ERO
subobject immediately prior to the ERO Hop Attributes subobject. If
the immediately preceding subobject is a label subobject [RFC3473],
the loopback SHOULD be enabled for the direction indicated by the U
bit of the label subobject.
