   You are asked to build redundant gateways in your EVPN-VXLAN environment, but you must conserve address space because these gateways must span across seven PEs. What should you implement on the PEs to satisfy these requirements?

   • AUse IRB interfaces with the same IP and MAC address.
   • BUse IRB interfaces with the same IP address and different MAC addresses.
   • CUse IRB interfaces with different IP addresses and the same VGA.
   • DUse IRB interfaces with the same IP and VGA.
