Abstract

This document presents considerations for link-layer addressing of Ethernet frames carrying MPLS-TP packets. Since MPLS-TP packets are MPLS packets, existing procedures ([RFC3032], [RFC5332]) for the encapsulation of MPLS packets over Ethernet apply. Because IP functionality is optional in an MPLS-TP network, IP-based protocols for Media Access Control (MAC) address learning, such as the Address Resolution Protocol (ARP) [RFC826] and IPv6 Neighbor Discovery [RFC4861], may not be available. This document specifies the options for the determination and selection of the next-hop Ethernet MAC address when MPLS-TP is used between nodes that do not have an IP data plane.

      MPLS Transport Profile (MPLS-TP) Next-Hop Ethernet Addressing

Abstract

   The MPLS Transport Profile (MPLS-TP) is the set of MPLS protocol    functions applicable to the construction and operation of packet-    switched transport networks.  This document presents considerations    for link-layer addressing of Ethernet frames carrying MPLS-TP    packets.
