This is the LSP restoration mechanism that Juniper have developed and
deployed. One of the main advantage is that the backup tunnels can be
initiated at head-end routers, thus there is no manual configuration at
intermediate routers. We have proposed two RSVP objects that are
backward compatible. Also since the detour paths are individually
established, there is no need to force labels to be globally assigned at
Please provide comments.

Title : A Method for MPLS LSP Fast-Reroute Using RSVP Detours

In this document, we introduce a method to establish backup LSP
tunnels in large-scale networks. Two additional RSVP objects are
proposed. These objects together make possible for routers using RSVP
to create detours that can route around downstream links and nodes.
As a result, an LSP can quickly and automatically repair itself,
while redirecting the user traffic to the pre-computed and pre-
established detour routes in event of network link and node failures.
Packet loss is therefore minimized.
