With reference to the exhibit, when Host A sends an ARP request for Host B’s IP address, which Junos feature does leaf1 need to send an ARP response to Host A without sending a broadcast frame across the fabric?

  • A proxy ARP
  • B GARP
  • C DAD
  • D proxy NDP
Explanation

EVPN distributes Host B’s MAC-IP binding to leaf1. When leaf1 finds the requested IP address in its MAC-IP binding database, Junos proxy ARP responds locally; ARP suppression prevents the ARP broadcast from being flooded across the EVPN fabric.
