   In a large EVPN-VXLAN fabric, an operator wants to ensure that Ethernet Segment routes (Route Type 4) for a specific ESI are only exchanged between the PEs that are attached to that ESI, and not advertised to the rest of the fabric. This is to reduce the control plane load. Which mechanism should be used?

   • AConfigure an ESI-Import Route Target on the Ethernet Segment routes
   • BUse BGP communities to filter the route
   • CUse a unique Route Distinguisher for the ESI
   • DConfigure a standard Route Target on the VNI
