A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : BGP Signaled MPLS Namespaces Authors : Kaliraj Vairavakkalai Minto Jeyananth Praveen Ramadenu Filename : draft-kaliraj-bess-bgp-sig-private-mpls-labels-06.txt Pages : 22 Date : 2023-07-10 Abstract: The MPLS forwarding layer in a core network is a shared resource. The MPLS FIB at nodes in this layer contains labels that are dynamically allocated and locally significant at that node. These labels are scoped in context of the global loopback address. Let us call this the global MPLS namespace. For some usecases like upstream label allocation, it is useful to create private MPLS namespaces (virtual MPLS FIB) over this shared MPLS forwarding layer. This allows installing deterministic label values in the private FIBs created at nodes participating in the private MPLS namespace, while preserving the "locally significant" nature of the underlying shared global MPLS FIB. This document defines new address families (AFI: 16399, SAFI: 128, or 1) and associated signaling mechanisms to create and use MPLS forwarding contexts in a network. Some example use cases are also described.
