This document presents an illustrative framework for providing fast
reroute in an IP or MPLS network through encapsulation and forwarding
to "not-via" addresses. The general approach described here uses a
single level of encapsulation and could be used to protect unicast,
multicast, and LDP traffic against link, router, and shared risk
group failure, regardless of network topology and metrics.
The mechanisms presented in this document are purely illustrative of
the general approach and do not constitute a protocol specification.
The document represents a snapshot of the work of the Routing Area
Working Group at the time of publication and is published as a
document of record. Further work is needed before implementation or
deployment.
This document is a product of the Routing Area Working Group Working Group of the IETF.
