  Per-Interface MIP Addressing Requirements and Design Considerations
                   draft-ietf-mpls-tp-mip-mep-map-05

Abstract

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

   This document is a product of a joint Internet Engineering Task Force
   (IETF) / International Telecommunication Union Telecommunication
   Standardization Sector (ITU-T) effort to include an MPLS Transport
   Profile within the IETF MPLS and PWE3 architectures to support the
   capabilities and functionalities of a packet transport network.
