NG-MVPN

Note:

This feature is currently supported exclusively on 7730 SXR platforms.

Multicast VPN (MVPN) or Next Generation IP Multicast in an IP-VPN (NG-MVPN) is an architectural framework that describes a set of virtual routing and forwarding (VRF) instances that support the transport of multicast traffic across a provider network.

MVPNs are defined in RFC 6513, Multicast in MPLS/BGP IP VPNs, and RFC 6514, BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs.

One key use case for NG-MVPN is in multicast-enabled mobile backhaul networks. In these deployments, BGP handles automatic provider edge discovery and customer multicast route advertisement.

The following list summarizes SR Linux support for NG-MVPN:

  • NG-MVPN auto-discovery
  • Customer multicast signaling (BGP)
  • Inclusive PMSI (IPMSI) with mLDP
  • Selective PMSI (SPMSI) with mLDP
  • Switching from I-PMSI to S-PMSI
  • P2MP LSP ping (mLDP OAM), see the ‟LSP ping for mLDP P2MP LSPs” chapter of the SR Linux OAM and Diagnostics Guide for more information.
