The IESG has received a request from the Multiprotocol Label Switching WG
(mpls) to consider the following document: - 'Refresh-interval Independent
FRR Facility Protection'
<draft-ietf-mpls-ri-rsvp-frr-07.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2019-11-05. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract

RSVP-TE Fast ReRoute extensions specified in RFC 4090 defines two
local repair techniques to reroute Label Switched Path (LSP) traffic
over pre-established backup tunnel. Facility backup method allows
one or more LSPs traversing a connected link or node to be protected
using a bypass tunnel. The many-to-one nature of local repair
technique is attractive from scalability point of view. This
document enumerates facility backup procedures in RFC 4090 that rely
on refresh timeout and hence make facility backup method refresh-
interval dependent. The RSVP-TE extensions defined in this document
will enhance the facility backup protection mechanism by making the
corresponding procedures refresh-interval independent and hence
compatible with Refresh-interval Independent RSVP (RI-RSVP) specified
in RFC 8370. Hence, this document updates RFC 4090 in order to
support RI-RSVP capability specified in RFC 8370.
