BESS Z. Zhang Internet-Draft L. Giuliano Updates: 6514 (if approved) Juniper Networks Intended status: Standards Track May 26, 2020 Expires: November 27, 2020 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).

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.

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 functionallyShow full document text
