Abstract Abstract
Segment Routing (SR) allows for a flexible definition of end-to-end Segment Routing (SR) allows for a flexible definition of end-to-end
paths within IGP topologies by encoding paths as sequences of paths within IGP topologies by encoding paths as sequences of
topological sub-paths, called "segments". These segments are topological sub-paths, called "segments". These segments are
advertised by the link-state routing protocols (IS-IS and OSPF). advertised by the link-state routing protocols (IS-IS and OSPF).
