MVPN and MSDP SA Interoperation
draft-ietf-bess-mvpn-msdp-sa-interoperation-05
Abstract
This document specifies the procedures for interoperation between
Multicast Virtual Private Network (MVPN) Source Active routes and
customer Multicast Source Discovery Protocol (MSDP) Source Active
routes, which is useful for MVPN provider networks offering services
to customers with an existing MSDP infrastructure. Without the
procedures described in this document, VPN-specific MSDP sessions are
required among the PEs that are customer MSDP peers. This document
updates RFC6514.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on November 27, 2020.

1. Terminologies
Familiarity with MVPN and MSDP protocols and procedures is assumed.
Some terminologies are listed below for convenience.
o ASM: Any source multicast.
o SPT: Source-specific Shortest-path Tree.
o C-S: A multicast source address, identifying a multicast source
located at a VPN customer site.
o C-G: A multicast group address used by a VPN customer.
o C-RP: A multicast Rendezvous Point for a VPN customer.
o EC: Extended Community.

2. Introduction
Section "14. Supporting PIM-SM without Inter-Site Shared C-Trees" of
[RFC6514] specifies the procedures for MVPN PEs to discover (C-S,C-G)
via MVPN Source Active A-D routes and then send (C-S,C-G) C-multicast
routes towards the ingress PEs, to establish SPTs for customer ASM
flows for which they have downstream receivers. (C-*,C-G)
C-multicast routes are not sent among the PEs so inter-site shared
C-Trees are not used and the method is generally referred to as "spt-
only" mode.
With this mode, the MVPN Source Active routes are functionally
