L3DL Upper Layer Protocol Configuration
draft-ietf-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.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

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:
