Segment Routing Configuration

Segment Routing(SR), also known as Source Packet Routing in Networking (SPRING), is a recent network routing paradigm covered by several complementary IETF drafts. The most fundamental are draft-ietfspring-segment-routing, draft-ietf-spring-segment-routing-mpls, draft-ietf-isis-segmentrouting-extensions, and draft-ietf-ospf-segment-routing-extensions.
SPRING is proposed as an alternative to LDP and/or RSVP-TE, segment routing is an emerging technology for IP/MPLS networks that enables source routing (SR), if you enable SR on your network no state is held in the network except the ingress SR router. This allow SR to scale significantly better then RSVP-TE while providing most the same functions, SR can offer IGP-based MPLS tunnels to services such as VPRN or VPWS without the addition of any other transport signaling protocol (Different with BGP-LU).
