The Security Considerations section says "It is assumed that this protocol is run in a well managed MPLS network with strict access controls preventing unwanted parties from generating MPLS OAM packets." While this is true of most (all?) MPLS networks, this assumption should also be stated in the abstract or Introduction as well.
