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 (LSP) Ping to bootstrap a BFD
session, optional control of the selection of a segment list as the
reverse direction of the BFD session, applicability of BFD Demand
mode, and Seamless BFD in the SR-MPLS domain. Also, the document
describes the use of the BFD Echo function with the BFD Control
packet payload.
