These segments are advertised by the link-state routing protocols (IS-IS, OSPFv2, and OSPFv3). ¶ [ RFC8402] defines the link-state IGP segments -- prefix, node, anycast, and adjacency segments.

What is the difference between IGP TOPOLOGY AND BGP …

WebIS-IS Extensions for Segment Routing Segment Routing (SR) allows for a flexible definition of end-to-end paths within IGP topologies by encoding paths as sequences of topological sub-paths called as Segments. These segments are advertised by the link-state routing protocols (IS-IS and OSPF). WebTo solve this, IGP is used in the ISP network to exchange specific topology information for reaching the next-hops within the ISP core. BGP advertises the external prefix with next-hop and IGP advertises the route to reach the next-hop. IGP handles all internal routes and BGP handles all global internet routes. khakis for women plus size
