1. A method of transporting a Multi-Transport Network Context Identifier (MTNC-ID), the method comprising:
receiving a data packet comprising an MTNC-ID in a data plane header of the data packet;
extracting the MTNC-ID from the data plane header of the data packet;
encapsulating the MTNC-ID in an argument field in a last segment of a segment list (SL[0]) of a segment routing version 6 (SRV6) header of the data packet;
encapsulating an instruction within a function field in the last segment of the segment list (SL[0]) of the SRV6 header of the data packet; and
transmitting the data packet over a SRV6 enabled data plane domain along a forwarding path corresponding to the MTNC-ID, wherein the MTNC-ID is associated with a set of resource provisioning requirements for one or more transport networks on the forwarding path to provision transport resources for forwarding traffic on the forwarding path.
