Hi Tissa, In section 10.1 in your draft of draft-tissa-nvo3-oam-fm-00, theory of operation is discribed, you say that originator device should specify the TTL of the transport header as 1 for the first request. Because transit devices in underlying network normally don't support the OAM function, if you specify TTL as 1, the first transit device will drop it, remote MEP or MIP won't receive the message if two or more hops exists between ingress and egress MEPs, so the response timer will expire on originator device. How can you ensure the OAM state machine on originator runs correctly in this scenario?
Thanks weiguo
