The framework for Operations, Administration and Maintenance (OAM) within the MPLS Transport Profile (MPLS-TP)(the MPLS-TP OAM Framework, [RFC6371]) distinguishes two configurations for the Maintenance Entity Group Intermediate Points (MIPs) on a node. It defines per-node MIPs and per-interface MIPs, where a per-node MIP is a single MIP per node in an unspecified location within the node and per-interface MIPs are two (or more) MIPs per node on each side of the forwarding engine.

          Addressing Requirements and Design Considerations for    Per-Interface Maintenance Entity Group Intermediate Points (MIPs)


   The framework for Operations, Administration and Maintenance (OAM)    within the MPLS Transport Profile (MPLS-TP) describes how the    Maintenance Entity Group Intermediate Points (MIPs) may be situated    within network nodes at incoming and outgoing interfaces.

   This document elaborates on important considerations for internal MIP    addressing.  More precisely, it describes important restrictions for    any mechanism that specifies a way of forming OAM messages so that    they can be targeted at MIPs on either incoming or outgoing    interfaces and forwarded correctly through the forwarding engine.    Furthermore, the document includes considerations for node    implementations where there is no distinction between the incoming    and outgoing MIP.
