This document extends Node and Link attribute TLVs to Interior Gateway Protocols (IGP) to advertise the Hop-by-Hop Options header processing action and supported services (e.g. IOAM Trace Option and Alternate Marking) at node and link granularity. Such advertisements allow entities (e.g., centralized controllers) to determine whether the Hop-by-Hop Options header and specific services can be supported in a given network.
