MPLS Network Actions (MNA)), this document describes a generic and extensible method to encapsulate extension headers into MPLS packets. The encapsulation method allows stacking multiple post-stack extension headers and quickly accessing any of them as well as the original upper layer protocol header and payload. We show how the post-stack extension header can be used to support several new MNAs and provide a generic alternative for some existing ones.}, }
