Refresh-Interval Independent RSVP Fast Reroute Facility Protection
RFC 9705

Received changes through RFC Editor sync (created document RFC 9705, created became rfc relationship between draft-ietf-mpls-ri-rsvp-frr and RFC 9705, set title to 'Refresh-Interval Independent RSVP Fast Reroute Facility Protection', set abstract to 'The RSVP-TE Fast Reroute (FRR) extensions specified in RFC 4090 define two local repair techniques to reroute Label Switched Path (LSP) traffic over pre-established backup tunnels.  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 a scalability point of view.  This document enumerates facility backup procedures in RFC 4090 that rely on refresh timeout, hence, making 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 the Refresh-Interval Independent RSVP (RI-RSVP) capability specified in RFC 8370.  Hence, this document updates RFC 4090 in order to support the RI-RSVP capability specified in RFC 8370.', set pages to 24, set standardization level to Proposed Standard, added RFC published event at 2025-03-26, created updates relation between RFC 9705 and RFC 4090)
