Abstract:
Segment Routing (SR) architecture leverages the paradigm of source
routing. It can be realized in the Multiprotocol Label Switching
(MPLS) network without any change to the data plane. A segment is
encoded as an MPLS label, and an ordered list of segments is encoded
as a stack of labels. Bidirectional Forwarding Detection (BFD) is
expected to monitor any existing path between systems. This document
defines how to use Label Switched Path Ping to bootstrap a BFD
session, control an SR Policy in the reverse direction of the SR-MPLS
tunnel, and applicability of BFD Demand mode in the SR-MPLS domain.
Also, the document describes the use of BFD Echo with BFD Control
packet payload.
