Introduction To Juniper Segment Routing With MPLS And OSPF (SR-MPLS)

What is Segment Routing and why should I use it? Segment routing is a method of source path routing which removes the need for a signalling protocol in MPLS such as LDP or RSVP, instead IGPs such as OSPF or IS-IS are extended to provide labels, meaning that transit routers do not need to maintain
