1. Introduction
[RFC3618] introduces the protocol definition of MSDP. This document
defines a YANG data model that can be used to configure and manage
the MSDP protocol. The operational state data and statistics can
also be retrieved by this model.
This model is designed to be used along with other multicast YANG
models such as PIM, which are not covered in this document.
2. Design of the Data Model
This model imports and augments ietf-routing YANG model defined in
[I-D.ietf-netmod-routing-cfg]. Both configuration branch and state
branch of [I-D.ietf-netmod-routing-cfg] are augmented. The
configuration branch covers global configuration attributes and per
peer configuration attributes. The state branch includes global, per
peer, and source-active information. The container "msdp" is the top
level container in this data model. The presence of this container
is expected to enable MSDP protocol functionality.

3. MSDP configuration
MSDP configurations require peer configurations. Several peers may
be configured in a mesh-group. The Source-Active information may be
filtered by peers.
The configuration modeling branch is composed of MSDP global and peer
configurations. The two parts are the most important parts of MSDP.
Besides the fundamental features of MSDP protocol, several optional
features are included in the model. These features help the control
of MSDP protocol. The peer features and SA features make the
deployment and control easier. The connection parameters can be used
to control the TCP connection because MSDP protocol is based on TCP.
The authentication features make the protocol more secure. The
filter features allow operators to avoid the irrelevant information.
4. MSDP State
MSDP states are composed of MSDP global state, MSDP peer state,
statistics information and Sa-cache information. The statistics
information and Sa-cache information helps the operator to retrieve
the protocol condition.
5. MSDP RPC
The part is used to define some useful and ordinary operations of
protocol management.
