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. module: ietf-msdp augment /rt:routing/rt:control-plane-protocols: +--rw msdp! +--rw global | +--rw connect-source? if:interface-ref | +--rw default-peer! {global-default-peer}? | | +--rw peer-addr leafref Liu, et al.

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. Liu, et al. Expires September 2, 2017 [Page 6] Internet-Draft MSDP YANG Model March 2017 6.
