Hello,
Why we are using multicast here in config if we are using MP-BGP EVPN?
As i know

  1. Traditionally, multicast has been used for broadcast and unknown unicast traffic replication in Layer 2 networks. However, VxLAN can leverage different mechanisms, such as BGP EVPN, to handle the control plane and eliminate the dependency on multicast for traffic replication.

  2. Multicast can indeed introduce additional load on network equipment, especially in large-scale deployments with a high volume of multicast traffic. By using VxLAN with BGP EVPN, you can reduce or eliminate the need for multicast replication within the overlay network. Instead, BGP EVPN allows for efficient and scalable control plane learning, where the information about MAC addresses and reachability is exchanged between the VxLAN endpoints using BGP. This approach can provide advantages such as reduced network complexity, improved scalability, and easier integration with existing network architectures.
