Traceroute to a SID is used for hop-by-hop fault localization as well as path tracing to a SID. Section 3 illustrates the ICMPv6 based ping and the UDP based traceroute mechanisms for ping and traceroute to an SRv6 SID. Although this document only illustrates ICMP ping and UDP-based traceroute to an SRv6 SID, the procedures are equally applicable to other IPv6 OAM probing to an SRv6 SID (e.g., Bidirectional Forwarding Detection - (BFD) [RFC5880], Seamless BFD (SBFD) [RFC7880], Two-Way Active - Measurement Protocol (TWAMP) [RFC5357], Simple Two-Way Active - Measurement Protocol (STAMP) [RFC8762], etc.).

IPv6 OAM operations can be performed with the target SID in the IPv6 destination address without SRH or with SRH where the target SID is the last segment. In general, OAM operations to a target SID may not exercise all of its processing depending on its behavior definition. For example, ping to an END.X SID (refer [I-D.ietf-spring-srv6- network-programming]) at the target node only validates availability of the SID and does not validate switching to the correct outgoing interface. To exercise the behavior of a target SID, the OAM operation SHOULD construct the probe in a manner similar to a data @@ -861,20 +862,32 @@ DOI 10.17487/RFC2119, March 1997, .
