Pseudowires need an inband control channel (CC) to do VCCV such that OAM and data packets follow the same path. PWs without a Control Word (CW) do not have an inband CC as defined in RFC5085. This document defines a simple extension to the TTL expiry CC (Type 3) to do inband VCCV. This can be used even without a CW.
