                      draft-ymbk-lsvr-l3dl-ulpc-00

Abstract

   This document users the Layer 3 Liveness and Discovery protocol to
   communicate the parameters needed to exchange inter-device Upper
   Layer Protocol Configuration for upper layer protocols such as the
   BGP family.

1.  Introduction

   Massive Data Centers (MDCs) which use upper layer protocols such as
   BGP4, BGP-LS, BGP-SPF, etc. may use the Layer 3 Liveness and
   Discovery Protocol, L3DP, [I-D.ietf-lsvr-l3dl] to reveal the inter-
   device links of the topology.  It is desirable for devices to
   facilitate the configuration parameters of those upper layer
   protocols to enable more hands-free configuration.  This document
   defines a new L3DP PDU to communicate these Upper Layer Protocol
   Configuration parameters.

2.  Reading and Terminology

   The reader is assumed to have read Layer 3 Discovery and Liveness
   [I-D.ietf-lsvr-l3dl].  The terminology and PDUs there are assumed
   here.

   Familiarity with the BGP4 Protocol [RFC4271] is assumed.  Familiarity
   with BGP-SPF, [I-D.ietf-lsvr-bgp-spf], might be useful.

3.  Upper Layer Protocol Configuration PDU

   To communicate parameters required to configure peering and operation
   of Upper Layer Protocols at IP layer 3 and above, e.g., BGP sessions
   on a link, a neutral sub-TLV based Upper Layer Protocol PDU is
   defined as follows:
