Techniques are presented for using a Loopback segment identifier (SID) that has the semantic of a Loopback address (terminate and process). Such a Loopback SID is assigned for both traditional SID and micro SID (uSID) that can be used in the segment-list of the probe packet to terminate the probe directly in the Nexthop of the adjacent SID (Adj-SID) which can be used to validate the forwarding semantic of the respective Adj-SID at the dataplane.
