MVPN Video 14 -    • MVPN Video 14 - BGP MVPN SAFI Part 1 - The...   CCIE/JNCIE IP Multicast Lecture Series -    • Lecture 1 - IP Multicast Basics and Addres...   This is the seventeenth video of a video series on Multicast VPNs (MVPN) and their implementation on both IOS and IOS-XR routers with a focus on CCIE candidate requirements. In this video, we further explore the Next Generation MVPN framework as defined in RFC 6513 (Next Generation MVPN Framework) and RFC 6914 (BGP MVPN). Our focus continues on RFC 6914 by introducing the C-Multicast Routes and the VRF Route Import extended Community. First we take a deep dive into the structure of the C-Multicast routes and the two different route-types: 1. Shared Tree Join route-type 2. Source Tree Join route-type We explore how these routes may case a very peculiar scaling problem if not equipped with mechanisms to improve their filtering at recipient PEs. Next we take a look at how the VRF Route Import extended community provides this filtering functionality. We take a deep dive into: 1. How the VRF Route Import extended community is advertised across the MVPN 2. How the MVPN PEs utilize this community for the C-Multicast route advertisement Next is the the Intra AS I-PMSI A-D route and how it helps the MVPN build Default MDTs in a flexible and scalable manner. After that, the video goes over scenarios with both Shared Tree Join and Source Tree Join routes to understand how the routes are constructed, how they use the VRF Route Import Community and how they are processed at the recipient MVPN PEs . Finally, the video demonstrates how end to end Shared Trees (Rendezvous Point Trees or RPT) and Source Trees (Shortest Path Trees or SPT) are created over the MVPN with the aid of the BGP MVPN C-Multicast routes.
