Abstract:
Segment Routing (SR) allows for a flexible definition of end-to-end
paths within link-state graphs by encoding paths as sequences of
topological sub-paths, called "segments".
The link-state routing protocols (IS-IS, OSPF and OSPFv3) have been
extended to advertise the segments. But flooding based propagation
of path segments using IGPs is limited by the perimeter of the IGP
domain. For building paths which span across IGP domains (e.g.
multiple ASes), the Border Gataway Protocol (BGP) is better suited as
its propagation perimeter is not limited like the IGPs.
This draft defines extensions to the BGP Link-state address-family to
carry path segment information via BGP.
