Hello everyone,

Now I’d like to share with you multicast VPN deploy mode.

As we know, there have two multicast VPN deploy mode:

1. Rosen mode

2. NG MVPN mode.

what is the difference bwtween the two modes? how to choose it?

The difference is as below:

Rosen MVPNs establish multicast distribution trees (MDTs) using Protocol Independent Multicast (PIM) to transmit VPN multicast protocol and data packets, and have the following limitations:

  • VPN multicast protocol and data packets must be transmitted using the MDT,  which complicates network deployment because the multicast function must be  enabled on the public network.

  • The public network uses GRE for multicast packet encapsulation and cannot  leverage the MPLS advantages, such as high reliability, QoS guarantee, and TE  bandwidth reservation, of existing BGP/MPLS IP VPNs.

Next-generation (NG) MVPNs, which have made improvements over Rosen MVPNs, have the following characteristics:
  • The public network uses BGP to transmit VPN multicast protocol packets and  routing information. Multicast protocols do not need to be deployed on the  public network, simplifying network deployment and maintenance.

  • The public network uses the mature label-based forwarding and tunnel  protection techniques of MPLS, improving multicast service quality and  reliability.

If the customer bandwidth is large enough to allow the public network to carry multicast traffic, you can choose the Rosen mode; if the customer wants to make better use of the various features of the MPLS network, they can choose NG MVPN mode.

This is what I want to share with you today, thank you!
