For example, an ingress device comprises one or more processors operably coupled to a memory that are configured to: in response to a request to verify connectivity of a segment routing LSP, configure a FEC stack specifying a stack of segment routing labels for the segment routing LSP; for each of the one or more devices identified from the FEC stack: generate a respective MPLS connectivity request packet for a respective device identified from an outermost FEC of the FEC stack; send the MPLS connectivity request packet to the respective device; receive an MPLS connectivity response packet that verifies connectivity of the respective device; and in response, update the FEC stack by removing the outermost FEC of the FEC stack that identifies the respective device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Segmented traceroute for segment routing traffic engineering","description":"Techniques are described for selectively pinging certain devices along a segment routing label switched path (LSP) to detect failures in the segment routing LSP.
