This document clarifies handling of the Traffic Class (TC) and Time- to-Live (TTL) fields of a Label Stack Entry that contains the Generic Associated Channel (G-ACh) Label (GAL). These clarifications are intended to aid interoperability of implementations. Original handling was defined in RFC 5586, and this document updates that RFC.
