A) In EVPN based VXLAN implementations, MAC addresses are propagated through BGP updates, which helps in efficient and scalable MAC address dissemination across the network.
C) The movement of a virtual host in an EVPN VXLAN environment triggers the dynamic remapping of the VTEP (VXLAN Tunnel Endpoint), ensuring that traffic is always routed to the current location of the host.
