Abstract
A node is configured to operate in a Segment Routing (SR) over Internet Protocol version 6 (SRv6) network, and the node includes circuitry configured to determine a Segment Identifier (SID) list for a forward path in the SRv6 network and SID list for a reverse path in the SRv6 network; and transmit a monitoring packet on the forward path including a Segment Routing Header (SRH) with the SID list for the forward path, and further including the SID list for the reverse path in the monitoring packet, for a SRH of a reply to the monitoring packet. The circuitry can be further configured to receive the reply to the monitoring packet, with the reply having been on a same or different tunnel as the monitoring packet, for monitoring liveliness thereof.
