This document defines extensions to BGP [RFC4271] to advertise the In-situ Flow Information Telemetry (IFIT) capabilities. Within an IFIT domain, IFIT-capability advertisement from the tail node to the head node assists the head node to determine whether a particular IFIT Option type can be encapsulated in data packets. Such advertisement would be useful for mitigating the leakage threat and facilitating the deployment of IFIT measurements on a per-service and on-demand basis.
