This document enumerates and describes the candidate schemes that can be used to indicate the presence of the MPLS extension header(s) following the MPLS label stack. The similar schemes are also applicable for indicating the potential in-stack extensions. After a careful evaluation of these options by comparing their pros and cons, it is expected that one should be chosen as the final standard scheme for MPLS extension indicator.
